Heat Treat Today publishes eight print magazines a year and included in each is a letter from the editor, Bethany Leone. In this letter, Bethany reports on her visit to the September meeting of Purdue Heat Treating Consortium where industry leaders presented key technical and operations decisions in heat treating. The academic partnership encourages research into topics such as sustainability and technology alternatives. Read more of what Bethany learned from her attendance at this dynamic and forward-looking consortium in this letter, which first appeared in the November 2024 Vacuum print edition.

What heat treat issue do you need fixed? At Purdue Heat Treating Consortium’s (PHTC’s) September meeting, I witnessed industrial manufacturers targeting key technical and operations decisions in heat treat through an academic partnership.
Since summer of 2022, the research driven School of Materials Engineering at Purdue has positioned itself as a partner to industrial leaders in the Midwest. Their main goal: advance research of precompetitive projects.
I spoke with one member who commented on the beginnings of PHTC: “Some of the Midwest, I’d say, user companies . . . wanted a Midwest school and more research-oriented university. To have Purdue be able to fill that was perfect; that’s some place that we recruit from, where we know has a lot of depth of professors that would be able to contribute, and which has facilities that would be able to be a part of. So, it was a really good partner to make that change with.”
At the recent quarterly meeting, I sat amongst several dozen representatives from Amsted Rail, Caterpillar, Cummins, Rolls Royce, ECM USA, and other member companies as we settled in for a day of research presentations. Foremost in members’ minds was feasibility in real world application.
Topics included developing sustainable quenchant alternatives and identifying a method for greenhouse footprint analysis that would meet standards. The presentations of ongoing research were each met with intent nods of satisfaction, questions scrutinizing the data, and proposals on what specific direction industry players wanted to see examined.
A mix of faculty and graduate students presented the five research topic findings. Guided by professors, the young people develop and execute research plans to address objectives determined by member voting at previous sessions. When I inquired what type of value this research held and the quality of the presenters, industry members were quick to speak highly of their abilities and the actionable research results.
Specifically, one member commented to me that the lifecycle work was proving to be helpful. Explorations like this give a “gauge of what we are able to meter on some of our own furnaces . . . and to have some common ways of describing emissions.” He continued, “that leads to either confirmation that we’re doing things right or to adjusting what we’re doing.”
Other topics that have been of interest address property variations when austempering certain materials and the quench oil work. Even when members may not apply all research results gained from the studies, ancillary work being done within a study — such as machine learning — offers additional value.
The group’s strength is collaborative action: as research objectives evolve, the academic contingent adapts. One paper was met with a peppering of cross-examination questions, the result being a large consensus as to the end value of this research. A plan to reconvene outside of regular sessions to provide industry testing data was determined, and industry members eagerly voiced their desire to contribute to this special moment.
Following presentations, the meeting came to a close. Voting members first determined which research to continue. Then, we toured the Manufacturing and Materials Research Laboratories at Purdue. The members witnessed various methods of metal 3D printing materials in action and handled printed parts of different alloy compositions.
Rounding out the day was an optional networking reception at a local pub and grill, Walt’s, where conversations around personal interests bled into reflections on research at PHTC.
My special thanks to Mark Gruninger, Managing Director for Industrial Consortia and Centers, and Mike Titus, Associate Professor of Materials Engineering and Technical Director of PHTC, for their invitation and warm welcome.
