Abstract: In discussions of sustainable or “green” design, the topic of weight reduction is often the first consideration.  Immediately, engineers of structural components turn to materials with low density such as aluminum and magnesium.  However, when strength and stiffness are taken into consideration, a low density material does not always result in a lower mass component or assembly.  Further, in the search to propel devices using less fuel energy, engineers can often lose sight of the total life-cycle energy of the material/process combination they have chosen in their design. High strength steels have made great advances, allowing their designs to compete with “lightweight” metals.  The steel manufacturers have done a good job communicating “new steel” to the design community.  However, the design community is largely unfamiliar with the light weight and low energy properties of Austempered Ductile Iron (ADI).  The lure of low specific gravity can lock design engineers into an improper material/process combination early in the design process to the exclusion of other, more efficient material/process combinations.  This paper will familiarize the reader with the concept of embodied energy and some of the environmental advantages of converting from a conventional material/process combination to an ADI casting solution.


 

Speaker: John is the owner and CEO of Applied Process Inc., an international group of commercial heat treats specializing in the Austempering process.  He graduated from the University of Michigan in 1977 with B.S. in both Mechanical and Materials/Metallurgical Engineering.  He is a Registered Professional Engineer.  John has a breadth of experience ranging from making gray iron blocks and heads to commercializing the single crystal casting process for super alloy turbine blades.  He is also the proprietor of Joyworks LLC, a metal casting studio located in Ann Arbor, MI. John has received numerous awards from, industry technical associations including, the American Foundry Society’s Wm. J. Grede Award (1998), an ASM International Fellowship (1998), the ASM Detroit Chapter Shoemaker Award (2000), the AFS Marketing Committee’s Jack F. Steele Award (2001), the American Foundry Society’s Ray H. Witt Award (2003), the University of Michigan Material Science & Engineering Alumni Award of Merit (2004) and the American Foundry Society’s Award of Scientific Merit (2005).  In 2008 John was honored to be named an Adjunct Professor to the Materials Science and Engineering Dept. at the University of Michigan where he is the Foundry Education Foundation Key Professor.  He is co-inventor on 9 patents and he is currently on the ASM Heat Treating Society Board of Directors.
