Our People

Heat Treat Today publishes twelve print magazines a year and included in each is a letter from the editor. This letter is from the September 2025 Annual People of Heat Treat print edition. In today’s letter, Bethany Leone, managing editor at Heat Treat Today, shares about the value of people in the heat treatment publication industry, highlighting individuals in the Heat Treat Today family.


We’re in business because people matter. Heat treating just happens to be our industry — which means we like making things hot (and then cold). But at our core, our business is people.

The Business of People

When I ask someone their favorite thing about the heat treating industry, most of the time, the answer is “the people.” Engineers, operations managers, sales reps, and operators all echo the theme.

Why is that? Maybe it’s the strong family values found in many family-founded, family-run operations. Or maybe the behind-the-scenes nature of the discipline draws a more people-focused crowd. It could be that the slower-paced, deliberate innovation attracts people motivated by collaboration more than competition. I’m not sure.

For whatever reason, it is a hallmark to our industry that those from various backgrounds and experiences can come to feel like family.

Welcome to the Family

Over the past year, we’ve welcomed several new individuals to the Heat Treat Today family. Each of them provides essential skills and abilities to making this publication helpful to you.

Jake Romano joined us in the summer of 2024. He embodies so many of our core values that it feels like he’s been here longer than just a year. Jake’s detailed eye for creative problem-solving has allowed our Heat Treat Radio podcast to reach new heights, funneling robust interviews to you seamlessly every month. He never fails to step up to the plate if time is of the essence and does so with the utmost professionalism and an ear for a good story: “My favorite thing that I’ve learned about the industry is just how diverse it is. There are so many people with fascinating backgrounds and reasons for joining the industry and I’ve been enjoying hearing their stories!”

Kelsha Wells has been the mastermind behind social media since fall of 2024 and recently coordinated the 40 Under 40 nomination process. The fruits of her labors are seen daily, connecting industry news and technical updates to you via social media. “From day one, I was struck by how incredible everyone is, not just in their talents, but in their willingness to support one another, celebrate wins, and work together seamlessly. That impression has only grown stronger over the past year.” This magazine edition is particularly special as she gets to see the many worthy young people featured on pages 36 to 71. She also supports various marketing campaigns for Heat Treat Today.

Michele Shaller found us through our legendary Laura Miller (now retired… we think). Michele assumed her position as editorial specialist in late-winter 2025. Every article you see in the print edition, every Heat Treat Radio transcript, and every, “hey, could you look at…?” piece of material gets an eagle-eye review by this whirlwind editor. Additionally, she is the editorial caretaker of several platforms, including the monthly e-newsletters.

Tiffany Ward connected with us in early spring 2025 and has been generating and formatting timely technical content for our website and Heat Treat Daily readers ever since. If you’ve ever had to scrap a heat treat plan and pivot fast under pressure, you have an idea of what Tiffany’s workday looks like every day. Can you say “pivot”?

Hamilton Pearman stumbled across the heat treat industry in 2014 and took a hiatus for a few years. Recently, he has returned, and in late-spring 2025, Hamilton assumed a sales role for Heat Treat Today’s European connections. Hamilton observed that the heat treat industry is like a large friendly family, “and that’s such a relief in the world we live today… Heat Treat Today is one the best examples of what I mean. Family, technical, focused, and yet still friendly.”

Mariah Roth, stepping into the critical role of administrative assistant as of this summer 2025, addresses the immediate challenges that our team faces. Fittingly, she commented the following: “Since joining the team, [I’ve been] realizing and affirming just how small the world is — this is something my grandpa had always said. The older I get, the more I understand this phrase. At the same time, I’m always learning how much I don’t know about the world. Coming from a metallurgy background to a heat treat industry, and now to a heat treat magazine company has really brought me full circle.”

What Is Hydrogen Embrittlement? Part 2

Ask The Heat Treat Doctor® has returned to bring sage advice to Heat Treat Today readers and to answer your questions about heat treating, brazing, sintering, and other types of thermal treatments as well as questions on metallurgy, equipment, and process-related issues.

This informative piece was first released in Heat Treat Today’s October 2025 Ferrous & Nonferrous Heat Treatments/Mill Processing print edition.

In today’s Technical TuesdayDan Herring continues his exploration of what hydrogen embrittlement is by contrasting it with other forms of embrittlement. Learn how to identify these various forms of brittle intergranular failure below!


We continue our discussion from last month concerning hydrogen-assisted cracking (aka hydrogen embrittlement) by looking at closely related phenomena, often mistaken for hydrogen embrittlement. Let’s learn more.

As a brief recap of what we discussed last month, the severity and mode of the hydrogen damage depends on:

  • Source of hydrogen — external (gaseous) or internal (dissolved)
  • Exposure time
  • Temperature and pressure
  • Level of residual and applied stresses
  • Type of alloy and its production method
  • Method of heat treatment
  • Treatment of exposed surfaces (barrier layers, e.g., oxide layers as hydrogen permeation barriers on metals)
  • Final treatment of the metal surface (e.g., galvanic nickel plating)
  • Presence of chemicals that may react with metals (e.g. acidic solutions)
  • Number of discontinuities in the metal

There are, however, several other embrittlement mechanisms that are often mistaken for hydrogen embrittlement and we will explore these here.

Quench Embrittlement

Contact us with your Reader Feedback!

Many high hardenability steels (e.g., 4140, 4340, 52100) are susceptible to a form of brittle intergranular failure from a phenomenon known as quench embrittlement. Under tensile or bending stress, higher carbon steels are susceptible to intergranular fracture in both the as-quenched condition and/or after low temperature tempering — generally considered “safe” from traditional embrittlement. A transition from ductile to intergranular fracture in martensitic steels having greater than 0.5% C can be embrittled even when tempered at low temperatures.

This phenomenon is different from tempered martensite embrittlement (TME) or temper embrittlement (TE), as explained below, as embrittlement occurs before tempering. The issue is exacerbated by the presence of certain embrittling elements (e.g., P, S, As, Sb, Sn, Pb) solely or when their combination reaches a high enough percentage (typically, 0.10%).

Temper Embrittlement

In broad based terms, TE involves a reduction in the normal ductility of a metal due to a physical or chemical change. TE is characterized by reduced impact toughness and occurs in certain quenched and tempered steels and even in ductile irons with susceptible compositions. This form of embrittlement does not typically affect room temperature tensile properties but causes significant reductions in impact toughness and fatigue performance. Although normally associated with tempered martensite, it can also occur if the matrix is tempered to the fully ferritic condition.

Types of Temper Embrittlement

When tempering steel, several types of embrittlement must be avoided. The first type, TME, is an irreversible phenomenon that can occur within 200−400°C (390−750°F). Years ago, it was called “blue brittleness” for the steel’s surface oxidation appearance, but this term is misleading since it can occur at temperatures below the onset of a blue coloration on steel.

Figure 1. Fracture modes in hardened steels

The second type is TE, a reversible phenomenon that occurs when steels are heated in and/or slow cooled through the temperature range of 375−575°C (705−1070°F).

Why Does it Happen?

TME and TE are examples of intergranular embrittlement. A common factor in such failures is the presence of elements that segregate to the grain boundaries. The chemical reaction rate or kinetics of segregation are such that they exhibit “C” curve behavior in the 350−550°C (660−1020°F) range; in other words, segregation does not occur uniformly. Both types of embrittlement are in part related to grain-boundary segregation of impurity elements (e.g., As, P, Sb, Sn), and both develop during thermal processing after austenitizing and quenching to martensite, usually indicated by an upward shift in ductile-to-brittle transition temperature.

TME is thought to result from the combined effects of cementite precipitation on prior-austenite grain boundaries or interlath boundaries and the segregation of impurities at prior-austenite grain boundaries. By contrast, TE is thought to be caused by the formation of carbides on decomposition of martensite, in particular, precipitation of carbides in the form of films at grain boundaries. At higher temperatures of tempering, this film disappears and cannot be restored on repeated heating at 250−400°C (480−750°F).

Which Steels Are Affected?

All steels are susceptible, so the real question becomes how susceptible and what factors affect that susceptibility. For example, while plain carbon steels may contain some of the same impurity elements that will cause the embrittlement phenomenon to occur in other steels, the segregation of these elements is often enhanced by or caused by the presence of other alloying elements in substantial quantities. As a result, alloy steels, in general, have more susceptibility than carbon steels.

It is important to understand that the degree of embrittlement is affected by the prior austenite grain size and hardness. So, if we are dealing with a fine-grained plain carbon steel of low hardness, it may not experience embrittlement symptoms despite its phosphorous content, whereas a more highly alloyed Cr-Ni steel used at higher hardness is more susceptible to its impurity content.

Widely used alloying elements, such as chromium, nickel, and manganese, tend to promote TE with the highest embrittlement effect observed in Cr-Ni and Cr-Mn steels. Small additions of molybdenum (0.2-0.3%) can diminish TE, while greater additions enhance the effect. TE can be prevented by keeping silicon and phosphorus levels as low as possible, adding up to 0.15% molybdenum and avoiding the embrittlement heat treating conditions.

Susceptibility also depends on impurity control and here is where the steelmaking process is critical. For example, in plain carbon and Cr-Mo steels (those with no Ni) where phosphorous is the most impactful embrittlement element, the percentage can be controlled by the steelmaking process. In steels that contain significant amounts of nickel, antimony and tin are more potent embrittlement elements. Phosphorous has an effect but not as large as it has in plain carbon and Cr-Mo steels. It should be noted, however, that antimony and tin in plain carbon steels can cause other hot working issues.

How Can We Correct It?

TME is irreversible, and its effects are permanent. By contrast, the effects of TE can be reversed. This is done by re-tempering above the critical temperature of 575°C (1070°F) then cooling rapidly. Impact toughness can be restored. If necessary, this process can be repeated.

A Simple Example

Alloy steel, which is susceptible to TE, will exhibit a relationship such as shown on Figure 2. Note that the impact toughness of quenched steel after tempering at 200−400°C (390−750°F) is lower than that obtained on tempering at temperatures below 200°C (390ºF). If brittle steel tempered in this range is heated above 400°C (750ºF) and transformed into a tough state, a second tempering at 250−400°C cannot return it to the brittle state. The rate of cooling from the tempering temperature range of 250−400°C has no effect on impact toughness.

Figure 2. Effect of temperature on impact toughness

The susceptibility of a given steel to TE depends on a number of factors, including grain size, hardness, steel grade, and the impurity control in the steelmaking process itself. Remember, not all steels and not all steelmaking processes are equivalent.

A heat treaters we must avoid the temptation to temper to a given hardness value without understanding the consequences of our actions. Since we do not have a simple embrittlement test that can be used on the shop floor, we must understand the phenomenon and question specifications that put us into TE ranges.

In Summary

The insidious nature of hydrogen embrittlement continues to cause concern and product failures during processing and during service, but as explained above, there are other heat treatment operations that can result in embrittlement. All of these and others (e.g., aluminum nitride embrittlement, overheating during forging, hot shortness) are responsible for many serious and in some instances catastrophic failures leading to injury or damage. All must be avoided.

Self-Learning Furnace System for Aluminum

The BatchPilot has transformed casthouse operations by increasing “right first time” batching.

“A furnace weighing system from Aluminium Casthouse Technologies (ACT) is now ‘self-learning’ to achieve higher production levels in casthouses. Knowing the correct weight of metal in the furnace is crucial to ensure slabs are consistently cast to the precise length ordered by the customer and the BatchPilot is used in casthouses worldwide to accurately measure furnace liquid metal weight. Determining exactly what is wanted aluminium and what is unwanted dross, it means casthouses don’t have to rely on visual estimates of furnace heel weight, which are unreliable. This often leads to short casts, overfilling of the furnace or potentially restricting the number of slabs cast, all hugely wasteful.”
