January 2025 Magazine
Now granted, heat treating isn’t in a romantic relationship, but this 2025, there are many relationships that have vied for the industry’s attention over the past decade plus. 2025 seems to be the year to scratch the itch that heat treaters have: Is it time to try something new?
Recently, Heat TreatToday released a poll on LinkedIn. We asked what the number one challenge that heat treat experts faced in the North American manufacturing industry. There were several big-ticket items that we offered: Precise temperature control, uniformity across large parts, managing furnace downtime and controlling residual stresses. Unsurprisingly, temperature control was voted as the top challenge of the four choices, though it was surprising that few respondents piped in on the topic of residual stresses.
Yet perhaps the most important engagement came from a commenter who addressed using legacy materials in changing industry requirements. How closely are we thinking about the future that materials — use of legacy materials as well as different legacy materials — have on our work in heat treatment? (Ok, your work. We all know that I’m leaving the discovery and application to you!)
As the commenter noted, the choices in the poll are all critical characteristics, and therefore factors heat treatment practitioners should already be concerned with. If you are looking at your heat treat operation’s relationship with a variety of processes and technologies and think that the relationship is ideal as can be, great.
But if you are in the “seven-year itch” camp — that is, there is some relationship with a process or technology that is on the rocks — this new annual magazine we are releasing each January highlights the heat treat technologies to watch for in 2025. It’s time to reevaluate the relationship your heat treat operations have with current technologies.
Technological Relationships Under Consideration
The heat treat industry is navigating a rapidly evolving landscape shaped by new materials and technologies. Additive manufacturing (AM), or 3D printing, introduces unique material requirements that challenge traditional heat treating. Complex geometries and the use of non standard alloys in AM demand processes tailored for uniformity and precision at an unprecedented level. These disruptions, coupled with constant innovations by researchers in materials science, are prompting a reevaluation of whether conventional heat treating methods are needed as is, or even at all. Check out the AM quiz on page 24 to get up-to-speed on some of these developments.
Meanwhile, robotics and AI are revolutionizing how operations are managed. AI-powered predictive maintenance is becoming indispensable, helping to minimize furnace downtime by identifying potential failures before they occur. Machine learning enhances furnace control systems by refining temperature cycles and gas flow in real time, ensuring consistency and efficiency. How are these systems working for heat treaters? Read the case study article on page 10.
Digitalization technologies, such as smart sensors and IoT-enabled systems, are making it easier than ever to monitor and analyze heat treating operations. These tools, combined with advanced software, empower operators to make data driven decisions and reduce energy consumption. Several articles in last month’s magazine release focused heavily on these technologies, but the conversation persists in the commentaries found on pages 17 and 27.
The question for 2025 is clear: Are heat treaters ready to adopt these innovations and adjust their processes to align with the needs of tomorrow’s manufacturing? Have your operations found the perfect relationship with these new technologies? Tell me what you’re finding to be most difficult to address in 2025 so we can examine that relationship in future editions.
Operating a hot isostatic press? The stages for HIP processing can become faster and more effective with gas detection technology. Learn about real-time leak detection analysis and continuous monitoring for outgassing.
ThisTechnical Tuesdayarticle byErik Cox, manager of New Business Development at Gencoa, was originally published inHeat Treat Today’sMarch/April 2024 Aerospaceprint edition.
The Problem in HIP
Hot isostatic pressing (HIP) is a widely employed method for densifying powders or cast and sintered parts. It involves subjecting materials to extreme conditions — high pressure (100–200 MPa) and high temperature (typically 1652°F–2282°F, or 900–1250°C) — in a specialized vessel.
Contact us with your Reader Feedback!Figure 1. Pumping times based on residual water vapor
One aspect of HIP comes before introducing metal or ceramic powders to the vessel: Operators must test for any leaks in the canisters. This ensures that the proper HIP processing can be completed. Secondly, outgassing of the powder must be performed, and thirdly, outgassing the HIP chamber should be done. All three are essential steps that are typically time consuming and inefficient, but new gas detection technology can make this pre-processing stage faster and more effective.
Real-Time Analysis for Leak Detection
Leak detection is normally performed with a helium leak detector, which are expensive and require significant technical knowledge to operate. Some HIP processing providers simply forego leak checking of the canister, fill the HIP canister with powder, and perform the degas; but in this case, any leaks will be identified during the degas process, and powder must then be removed to repair the canister.
HIP users must look to technology that effectively detects leaks before they proceed to outgassing. One example of this is Gencoa’s Optix gas sensor: As the pumping procedure commences and pressure reaches 0.5 mbar (which typically occurs within 15–30 seconds), the device switches on and employs a sophisticated analysis of the nitrogen that enters the canister from the atmosphere to discern the leak rate of the canisters. When a leak is detected, argon gas can be sprayed around the canister to accurately detect the leak point and allow repair.
Outgassing: Traditional vs. Continuous Monitoring
Outgassing is a critical step in the preconditioning of powders for HIP processed components, involving the removal of adsorbed gases and water vapor from the metal powder through vacuum pumping. Traditionally, the endpoint for this process is not monitored, leading to an overly long vacuum pumping stage of up to several days to ensure that the powders are correctly prepared.
Th is challenge is addressed by providing continuous monitoring throughout the entire degassing process, reducing the time to degas through the ability of the Gencoa Optix gas sensor to precisely determine the degas endpoint.
Figure 2. Gencoa Optix
By offering real-time feedback and notifying users when degassing is complete, this sensor saves time and ensures the production of high-quality components with traceability. With the Optix, one user saw their degas times reduced from 24 hours to 4 hours. The sensor is capable of residual gas analysis, providing a comprehensive solution for improved productivity. Its wide-range pressure measurement capabilities, coupled with efficient leak checking of HIP processing enclosures, further enhance the overall operational efficiency.
Optix operates as a highly sensitive, stand-alone device that utilizes a small plasma (“light”) that detects the gas species present. This design ensures that the detector remains impervious to contamination or vacuum issues, maintaining continuous monitoring and avoiding potential damage. Because the device also eliminates the need for filament replacement or disassembly of components for maintenance, the design will perform at 100% operational uptime even in the harshest environments.
Indispensable Tools for HIP Processing
HIP operators need to maintain equipment efficiently and effectively, and technologies that integrate solutions not only enhance overall productivity, leak detection, and control of the degassing process, but are indispensable to improving the overall quality and traceability of components. Leveraging technologies that allow for early detection and increase uptime will only enhance the future HIP can offer to the AM-focused aerospace industry.

The race to space is in full swing with public and private sector companies staking their claim in this new frontier. And breakthroughs in technology and materials offer the potential to propel humanity to unprecedented distances. Success hinges not only on the ability to discover novel solutions but also on the capacity to prepare those solutions for efficient, large-scale production.

Space Today: Making Life on Earth Better, Safer, and More Connected
Noel Brady, Metallurgical Engineer, Paulo Source: Paulo
According to NASA, 95% of space missions in the next decade will stay in low Earth orbit (LEO) and geostationary orbit (GEO). Th at means the first wave of commercial activity in space will be largely focused on making life on Earth better.
Several worldwide broadband satellites are already in orbit, offering more consistent, reliable internet signals around the globe. Defense campaigns are using advanced satellite machine learning to improve asteroid and missile detection, along with revolutionary laser technology that has made intersatellite communication possible for the first time — and the travel of information faster. And to help make life in space safe and successful, NASA is developing a scalable network of public GPS receivers for easy, short-range space navigation and tourism.
All this to say, parts are being developed for a wide range of applications, a huge portion of which are being additively manufactured.
Thermal Processing Standards Necessary for AM Adoption
However promising additive manufacturing is for space, the adoption of AM has still been limited due to the lack of standards for proprietary material and 3D printing applications. Many thermal processing experts are joining research institutions and OEMs in the drive to bring AM into mainstream manufacturing with new industry standards and production-ready solutions that help achieve ROI.
The R&D process for discovering these standards can be lengthy and expensive because it requires trial and error. A prototype or small run of parts must be manufactured, then heat treated, and tested for the desired properties. If a test part’s yield strength is not where it should be, for example, then the heat treating recipe is adjusted, perhaps by lowering the temperature and increasing the pressure, and can be tested again on a new batch of parts.
Coach vs. Custom Cycles
In heat treating, there are two different types of cycles, and it’s important to know the difference when you’re working with any commercial heat treater. Coach cycles tend to be more economical because these are shared cycles — existing recipes that are in high demand and run on a regular schedule — with the potential to have multiple clients’ parts in the furnace at once. For example, a heat treater may have a standard titanium coach cycle they run once a day. See Table A for several coach cycles run at Paulo.
Table A. Example of Coach Cycles for Space Alloys
Coach cycles use recipes that were designed for cast parts and have been around since before additive was a viable form of manufacturing. While it’s true that cast parts and AM parts have similarities, such as their high porosity, it doesn’t mean that the recipes are optimal for preparing today’s parts for heavy space applications. That’s where custom cycles come into play.
Custom cycles are ideal for new or proprietary materials that don’t yet have recipes defined or that are not commonly heat treated enough to run on a regular schedule. The distinction between the two is important because not all heat treaters are equipped to run both types. While you may be able to find a coach recipe that gets you close to where you need to be, it certainly may not be optimal, especially for parts that will have a heavy life of service.
Heat treaters with flexibility of custom and coach cycles, along with full-cycle data reporting, offer a high level of control that is vital for helping the industry progress and scale for production. This is also a big reason why some in-house heat treating operations may choose to outsource some of their work: first collaborating with experienced commercial heat treaters to prove the specification for a new part with custom cycles before scaling for production.
Common Cycle Adjustments for AM
There are five primary parameters that can be adjusted in the heat treating of AM parts to achieve the desired results: temperature, pressure, time, cooling rate, and heating rate. For AM parts, adjustments to the temperature and pressure are a go-to for achieving parts with higher yield strength. For example, running a cycle 50°F cooler, but at 5 ksi higher pressure may yield better results.
There may also be certain heating ramp rates and intermediate holds before parts get to the max temperature, to allow for consistent heating and enhance the material properties. The same goes for the cooling process: controlling the rate at which a part cools with specific holding times and intermediate quenches.
Hot Isostatic Pressing, Space, and Additive Manufacturing
Hot isostatic pressing (HIP) combines high temperature and pressure to improve a part’s mechanical properties and performance at extreme temperatures. The sealed HIP vessel provides uniform pressure to bring parts to 100% theoretical density with minimal distortion. The high level of control and uniformity has made HIP the gold standard for AM parts for space.
Similar to cast parts, 3D-printed materials tend to have porous microstructures that can compromise part performance. HIP is the only process that’s able to eliminate these pores without compromising the complex geometries and near-net dimensions that are achieved in the printing process.
Benefits of HIP for space parts include the following:
Better fatigue resistance
Greater resistance to impact, wear, and abrasion
Improved ductility
For this process, Paulo’s Cleveland division is equipped with a Quintus QIH-122 HIP vessel, which is specially modified with additional thermocouples for more precise temperature control and greater data collection. A higher level of accuracy allows us to iterate with confidence and find an efficient path to production-ready development.
One primary benefit of the Quintus QIH-122 HIP is the ability to have faster cooling at a controlled rate, which allows you to heat treat and solution treat in one furnace. This cooling rate allows great efficiency that cannot be seen with other HIP vessels on the market.
It is critical that heat treaters adapt to meet the needs of this fast-evolving industry. Many commercial heat treaters do not yet have the level of data or dynamic cycle offerings necessary and will only run HIP coach cycles with set parameters. In other words, many are not equipped to economically iterate and adapt heat treating recipes for new parts. Without custom cycles, controlled cooling, and a higher level of data, it is impossible to push the boundaries of what’s possible.
Space Parts Requiring Thermal Processing
The future of space travel requires parts that can not only perform under high levels of mechanical pressure and extreme temperatures but are also durable enough for long-range and repeat missions. Heat treatment is a critical step in preparing rocket engine components, among others, for commission. Other space components commonly heat treat treated are:
Volutes
Turbine manifolds
Bearing housings
Fuel inlets
Housings, support housings
Bearing supports
Turbo components
Since the inception of NASA’s Space Shuttle Program, Paulo has treated integral components for launch and propulsion, along with many parts currently in orbit on the International Space Station.
Materials Used in Space Parts
New materials and applications are being explored every day. Proprietary alloy blends bring unique properties and promising potential in the push for stronger, faster, longer-lasting parts. But with unique properties comes the need for unique heat treating processes. Several high-performance superalloys used for space include:
Inconel 718, 625
Titanium (Ti-6Al-4V)
Hastelloy C22
Haynes 214, 282
GRCop Copper
Inconel 718, a championed space alloy, was originally used as a premier casting material before being adopted for AM. This nickel-based material features an extremely high tensile and yield strength that makes it ideal for components taking on a high mechanical load in extreme environments ranging from combustive to cryogenic — making this a natural material to adopt for space in the early days of 3D printing.
Because casting and 3D printing both result in similar porous microstructures, the heat treating process used for Inconel castings could also be adapted. Finding new opportunities within existing alloys like this is a highly efficient way to gain material advantage in today’s race to space.

Cemented carbide is often used interchangeably with other terms in the industry to describe a popular material for tool production. However, the specifics of what makes up a cemented carbide, and how this material can be processed, are not so widely discussed.
In this best of the web article, discover the composition, applications, and processes involved in sintering cemented carbide, as well as how vacuum furnaces play an essential role for this material. You will encounter helpful diagrams and resourceful images depicting each step of the process.
An Excerpt:
“Hard metal, or cemented carbide, refers to a class of materials consisting in carbide particles dispersed inside a metal matrix. In most cases, the carbide of choice is tungsten carbide but others carbide forming element can be added, such as tantalum (in the form of TaC) or titanium (in the form of TiC). The metal matrix, often referred as ‘binder’ (not to be confused with wax and polymers typically used in powder metallurgy) is usually cobalt, but nickel and chromium are also used. This matrix is acting as a ‘cement,’ keeping together the carbide particles (hence the ‘cemented carbide’ definition).”
Metal 3D additive manufacturing has grown dramatically in the last five years. Nearly every metal printed part needs to be heat treated, but this presents some challenges. This article will address some of the challenges that a heat treater faces when working with these parts.
This Technical Tuesday article, written by Mark DeBruin, metallurgical engineer and CTO of Skuld LLC, was originally published in December 2023’sMedical and Energy magazine.
Mark DeBruin Metallurgical Engineer and CTO Skuld LLC
In my experience, on average, about 10% of all 3D metal printed parts break during heat treatment; this number varies depending on the printer and the unique facility. While materials can be printed with wire or even metal foils, I’m going to mainly focus on the approximately 85% of all metal 3D printed parts that are made from metal powder and either welded or sintered together.
Most metal printed parts normally have heat added to them after printing. In addition to the heat of the printing process and wire electrical discharge machining (EDM) process to separate the part from the build plate, heat may be added up to five times. These steps are:
Burnout and sintering (for some processes such as binder jet and bound powder extrusion)
Stress relieving
Hot isostatic pressing (HIP)
Austenitizing (and quenching)
Tempering
3D printing can create a non-uniform microstructure, but it will also give properties the client does not normally desire. Heat treating makes the microstructure more uniform and can improve the properties. Please note that heat treating 3D printed parts will never cause the microstructure to match a heat treated wrought or cast microstructure. The microstructure after heat treating depends on the starting point, which is fundamentally different.
If the part is not properly sintered, there is a high chance it will break during heat treatment. It may also exhaust gases, which can damage the heat treat furnace. The off gases will recondense on the furnace walls causing the furnace to malfunction and to need repair. This can potentially cost hundreds of thousands of dollars.
During powder 3D printing, there is a wide variety of defects that can occur. These include oxide inclusions, voids, unbonded powder, or even cracks that occur due to the high stresses during printing. Even if there are not actual defects, the printing process tends to leave a highly stressed structure. All of these factors contribute to causing a print to break as the inconsistent material may have erratic properties.
In a vacuum furnace, voids can be internal and have entrapped gas. Under a vacuum, these can break. Even if something was HIP processed, the pores can open up and break. Even if they do not break and heat is applied, the metal will heat at different rates due to the entrapped gas.

There are also issues during quenching due to the differences in the surface finish. In machining, the surface is removed so there are not stress concentrators. In 3D printing, there are sharp, internal crevices that can be inherent to the process that act as natural stress risers (see Figure 1). These can also cause cracking.
When 3D printed parts break, they may just crack. This can result in oil leaking into the parts, leading to problems in subsequent steps.
Figure 2. Example wire mesh basket (Source: Skuld LLC)
However, some parts will violently shatter. This can happen when pulling a vacuum, during ramping, or during quenching. This can also cause massive damage to the furnace or heating elements. It can potentially also injure heat treat operators.
A lot of heat treaters protect their equipment by putting the parts into a wire mesh backet (Figure 2). This protects the equipment if a piece breaks apart in the furnace, and if a piece breaks in the oil, it can be found.
Print defects in metal 3D printed parts can be a challenge to a heat treater. Clients often place blame on the heat treater when parts are damaged, even though cracking or shattering is due to problems already present in the materials as they had arrived at the heat treater. As a final piece of advice, heat treaters should use contract terms that limit their risks in these situations as well as to proactively protect their equipment and personnel.

"SLM"? You may have heard of AM -- additive manufacturing -- but how about selective laser melting, SLM? Stay on top of your acronyms with this overview on how vacuum furnaces and SLM, an AM technology, can increase fatigue performance of parts.
In this Technical Tuesday, the author not only shares what this technology can do, but also the results of SLM in laboratory studies and research at the University of Parma.
"When SLM processes are conducted within a vacuum heat process, it is possible to make more detailed components which have more intricate forms. Crucially, this means that they will often perform better than would otherwise be the case when they are in use."
Canada’s Burloak Technologies will use hot isostatic press (HIP) technologies to push the limits of additive manufacturing (AM) to deliver new levels of mechanical performance and strength properties in parts for mission-critical applications. Providing rapid cooling under pressure will minimize thermal distortion and non-uniform grain growth in components, producing finished parts with optimal material properties and allowing Burloak to significantly increase production.
Peter Adams Founder and Chief Innovation Officer Burloak
As a full-service additive manufacturer, Burloak works with innovative companies in the space, aerospace, automotive, and industrial markets to rapidly transition their most challenging part designs to be additively manufactured at scale. The High Pressure Heat Treatment™ (HPHT™) capability of the new QIH 60 M URC™ HIP from Quintus Technologies facilitates this rapid transition. Combining high pressure, heat treatment, and cooling in a single process makes it possible to remove several operations from the AM production line, generating significant savings in both cost and time. Additionally, the press’s highly customizable cooling cycle can be programmed to stop at a specific temperature while maintaining the desired pressure set point.
The press's capability to rapidly cool under pressure, "is critical for Burloak as a full-service supplier for all customers, and, in particular, for the development of high-strength flight components," comments Peter Adams, founder and Chief Innovation Officer at Burloak. "Without this in-house capability, outsourcing this process would slow down our project timelines, add complexity to our processes, and risk damaging critical customer components as they would need to be shipped internationally."
The model QIH 60 press features a hot zone of 16.14 x 39.37 inches (410 x 1,000 mm), an area large enough to process any component printed on most powder bed machines, Mr. Adams notes. It operates at a maximum temperature of 2,552°F (1,400°C) and maximum pressure of 207 MPa (30,000 psi).
"We are very pleased to be chosen as their strategic partner in furthering the development of additive manufacturing," says Jan Söderström, CEO of Quintus Technologies, "and we look forward to sharing our applications expertise through our Quintus Care program."
Heat treat methods are going to change in more ways than one, claims Dilip Chandrasekaran, head of R&D and Technology at Kanthal. “What we’ll see in the future as the industry grows is more automated processes where 3D printers feed parts into post-treatment. It will need to be smooth and streamlined, and the heating will need to perform different processes.”
