Metalcasting Industry Roadmap
She realized that to further optimize casting designs, simulations required available and accurate high temperature thermo-physical property data.
As Shelly was earning her Masters in Material Science and Engineering at the Illinois Institute of Technology, she researched and developed high temperature creep curves for a martensitic grade of stainless steel. These creep properties now make it possible to simulate the casting distortion and stresses during the steel heat treatment process and to provide more accurate prediction of the occurrence of hot tears during solidification.
For accurate prediction in simulation, the
properties of the mold materials are just as important. Shelly worked with her original mentor at UNI on the research published in the AFS transactions, "High Temperature Physical Properties of chemically Bonded Sands Provide Insight in to Core Distortion and Provides New Data for Casting Process Simulation" which was given the Howard Taylor Award for Scientific Merit at the 115th AFS Metalcasting Congress.
Shelly is currently serving on the Foundry Education Foundation Academic Advisory Board for UNI's metal casting program, and she is a member of the Society of Women Engineers, SWE. She has volunteered for GEMS (Girls in Engineering Math and Science), Expand Your Horizons (SWE), and Girl Scout STEMPalooza events to support young women's introduction to the metalcasting industry in make molds and pouring metal castings. Shelly will continue to believe that supporting the education of and encouraging the next generation is a high priority of the future of metal casters.
Kathy L. Hayrynen
Director of Research & Development, Applied Process Inc. - Technologies Division, Livonia, MI
khayrynen@appliedprocess.com (734) 464 8000 ext. 232
Kathy has a BS, MS and PhD in Metallurgical Engineering from Michigan Technological University. Her graduate studies were focused on production of ductile iron and austempered ductile iron (ADI). Following her graduate work, she completed a post-doctoral research program for the US Army Tank Automotive Command on combining mechanical deformation steps with ADI for use on track systems for armored vehicles in conjunction with the Keweenaw Research Center and Michigan Tech.
Kathy joined the Applied Process Companies in 1995 as the Technical Director and now serves as the Director of Research & Development. The Applied Process Companies are a group of commercial heat treat facilities that focus on helping customers develop innovative austempering solutions to engineering challenges. During her tenure
commercializing Carbidic ADI, Carbo-AustemperedTM steel and LADITM (localized ADI).
Kathy has had a broad breadth of experience with AFS on multiple fronts. Her MS program was AFS sponsored research so she understands how that relationship functions. She is a past-Chair of the 5I Committee (Ductile Iron Research Committee) as well as a past-Chair of Division 5
