Novel Mechanical Testing Systems Powered By Finite-Element Analysis, Optimization Algorithms, and Machine Learning

- An excerpt from a Heat Treat Radio episode with James Dean -

Doug Glenn:  You may have already stated this a little bit, but briefly: indentation plastometry is basically taking an indentation to be able to test, not just hardness or not even necessarily hardness, but the deformation or the strain of material.  Do you have to know the microstructure of the material when you’re doing these tests?

James Dean:  That’s a good question.  In principle, no.  If we were to dig deep into the mechanics of what’s going on within our system and our software package, you’d come to recognize that it’s, from a mathematical point of view at least, insensitive to microstructural features.  There is a numerical method underlying this – a finite-element analysis – therefore, treating this as a continuum system doesn’t take account explicitly of the microstructure.

When you’re doing the test, it’s actually helpful to know something about the microstructure simply because our technology is all about extracting bulk mechanical behavior engineering properties.  Therefore, when we do our indentation test, it is important that we are indenting a representative volume of the material.

It is important that we are capturing all of the microstructural features that give rise to the behavior you would measure in a microscopic stress strain test.  Otherwise, you can’t pull out those bulk, core engineering properties, and therefore, the scale on which you do the indent is important.  Your indenter has to be large relative to the scale of the microstructure.  So, it’s only at that level that you need to understand or know anything about the microstructure.

DG:  This test is a nondestructive test, right?  You said you can actually test live materials, correct?

JD:  Yes.

DG:  You don’t have to destroy them, you don’t have to machine them, you don’t have to make them into something you can rip apart, right?

JD:  Right.

Bert demonstrates the benefits of working with a collaborative robot to induction harden steel parts. The robot gives the operator the ability to work directly next to it, as opposed to conventional robot arms where fencing and distance is required.

Robotic Revolution

- An excerpt from Metal Treating Institute Member Profiles with Penna Flame Industries -

The computerized robotic surface hardening systems have revolutionized the surface hardening industry. These advanced robots, coupled with programmable index tables, provide an automation system that helps decrease production time while maintaining the highest quality in precision surface hardening.

A few benefits of this service are:

  • Increased wear resistance
  • Higher hardness and longer life
  • Less processing time
  • Higher efficiency and productivity
  • Maintain tensile strength
  • Quick turnaround of the project
  • Consistent, repeatable process
  • Less distortion when compared to furnace treatment

High Pressure Break Through For Additive Manufacturing

- An excerpt from a Heat Treat Radio episode with Johan Hjärne -

DG:  Doing it all- stress relief, HIP, age, or whatever. Just for clarity sake, you’ve got a typical HIP process, you’re going to heat it up, put it under very high pressure, then, normally, if you didn’t have the high pressure heat treatment capabilities, you would have to cool that part down which is typically cooled quite slowly in a conventional HIP unit, taking more time and whatnot.  It then comes down to ambient, or close to ambient, where it can be held, you take it out, you put it back in another furnace (a normal furnace, not a HIP furnace), take the temperature back up, get it to the point where you want it, quick cool it, quench it, to a certain extent, to get the characteristics that you’re looking for, and you’re done.  What we’re talking about here is the combination of those two processes plus potential other things like stress relief, and all that, in a single unit, correct?

JH:  Yes.  This has very beneficial effects on time.  Many of the HIP vendors do not have HIP and heat treatment in the same facility.  Now we have sold a couple of units to some new HIP vendors that have this capacity, but, historically, the HIP vendors didn’t have both HIP and heat treatment.  First, the customer had to send it to a service provider for HIPing, they got the part back, they had to send it to somebody that could do the heat treat step, and then got the part back, and so on.  The time, and specifically for additive manufacturing, is important.  Keep in mind they can do a part pretty fast, anywhere between a day to two days, worst case a week, but then having to wait week after week after week to get the part back for the HIPing or for the heat treating.

DG:  So there’s a substantial, potential time savings, for sure; not just process savings in between furnaces, but the fact that you can buy one furnace and do both of those things.

Let’s talk for just a second about what types of products are most effectively HIPed and/or, if we can, high pressure heat treated.

JH:  As I said before, we really started to realize the potential with this technology with the additive manufacturing world.  That is were we started to realized that we can actually make a difference here.  Not only does it have a beneficial effect for the total time, but having the components under elevated temperature for a shorter period of time is actually beneficial for the microstructure; the grain doesn’t grow as much.

Modernizing Tech

- An excerpt from Metal Treating Institute Member Profiles with Franklin Brazing and Metal Treating -

Recent improvements include a new cooling tower, chiller system, enhanced duct work, LED lighting in the plant, a renovated breakroom for the associates, a quality room for the engineering staff, a new HVAC system for the front offices, and upgrades in technology systems.

The updated technology is not only used for improving efficiency and data analysis, but also for communication. It has been key to improving operations and has had a significant impact on relationships with clients. Franklin’s ability to effectively communicate enhances collaboration, which allows FBMT’s clients to more efficiently manage their supply chains, reduce the cost of rework and scrap, and better serve their clients.

Franklin Brazing and Metal Treating

Although Franklin Brazing and Metal Treating (FBMT) was founded in the 1960s, the current owners, Timothy and Margaret (Peg) Mathile purchased the company in October of 1995. In 2000, they invested in building a 51,000 square foot permanent facility located in Lebanon, Ohio.

On June 1, 2017, Peg was made majority owner of the partnership and became intimately involved in the business. As an owner/operator, however, she saw the need to “refound” Franklin Brazing and Metal Treating. “It is wonderful to have history and longevity, which proves that there is enough capital for the company to continue; but what is most important is who Franklin Brazing is today,” she said.

According to Peg, “I didn’t really have experience in manufacturing or heat treating, but I sensed that no matter how great our facilities or systems were, if I didn’t have the right people in the right place with the right attitudes, nothing else would matter. So, for the first several years, I focused on culture and people first and foremost, with an eye on facilities and systems improvements. I also believe that everything is about relationships, regardless of the industry.”

That focus on relationships became a driving force in the company’s values of teamwork, excellence, integrity, and respect in every aspect of Franklin’s culture. There is a palpable energy throughout the organization that comes from honoring its values as well as a commitment to quality systems and continuous improvement. Peg believes in the adage, “Don’t just tell me, show me.”

Franklin Brazing and Metal Treating provides annealing, assembly, and brazing services using continuous belt furnace brazing with pure atmospheres. FBMT works with carbon and stainless-steel parts that are needed for the automotive, heavy trucking, agriculture, medical, food service, and aerospace industries. The true value-add at Franklin is that the services are performed by seasoned full-time associates who have a deep understanding and experience of the processes and what it takes to produce good parts.

FBMT places a high priority on education and training. There is a commitment to enhance the associates’ knowledge through investing in educational opportunities and training. “We have a wonderful team and when opportunities are provided for people to grow, everybody wins,” Peg said. “The associate wins, the company wins, and most importantly, our clients win.”
