In 1972, Todd lived for a year in the remote highlands of South-West Ethiopia among the Deemay people, who were producing iron by methods used 2000 years ago. In her presenta- tion, Todd took the group on a virtual trip back to the Afri- can Iron Age to learn about the importance of iron not just for tools but in warding off the “evil eye,” the daily life of the Deemay, and the position of the smith caste in society. The role of inclusion analysis in determining patterns of trade in iron artifacts was also discussed. Todd is P.B. Breneman Chair and professor of ESM at Penn State University. Brandywine Delves into Materials Data Lesley Frame was the featured speaker for the Brandywine Chapter’s third technical meeting of the season. Her December 8, 2020, talk on “Mater- ials Data for Process Modeling” ad- dressed some of the current challenges associated with selecting and collect- ing materials data as inputs to multi- scale behavior models of materials for thermal and mechanical manufac- turing processes. Deterministic and stochastic approaches were discussed along with the need for uncertainty quan- tification of simulation results. Ongoing research by the Center for Materials Processing Data (CMPD) was presented as an example of some of these materials data challenges. ASM International serves as the business administrator for CMPD. Frame is director of the CMPD and assistant professor of MSE, University of Connecticut. NY/NJ Hosts Biomedical Expert On December 10, 2020, the NY/ NJ Chapter hosted a virtual technical talk on “Implantable Materials for Car- diovascular Applications Research” presented by Andrey Zakharchenko, a postdoctoral fellow in the laboratory of Dr. Robert Levy at the Children’s Hos- pital of Philadelphia. He shared that although bioprosthetic heart valves made from animal-derived materi- als often work for many years in adults, they tend to fail in children as early as within one year due to valve calcifica- tion and structural degeneration. Zakharchenko discussed a new valve coating procedure using a biocompatible and non-immunogenic polymer, polyoxazoline (POZ) developed by his team. The use of POZ helps block the accumulation of serum proteins, stabilizes inner collagen structure, and improves fluid performance of the valve. Zakharchenko specializes in bioprosthetic heart valve research and investi- gates the failure mechanisms of biomaterials used in these devices. His research interests include development of new biomaterials in medicine, novel therapies for heart valve disease, and nanomedicine. Hartford Holds Titanium Talk The ASM Hartford Chapter’s Jan- uary 12 meeting saw a 36% increase over their average attendance. Par- ticipants in the virtual meeting hailed from a wide geographic area including Albany, Los Angeles, Seattle, and Van- couver. The chapter, which celebrated 100 years in October 2020, saw a lot of positive energy from this meeting. The technical talk on “Advances in Titanium MIM & Additive Manufacturing” was presented by Joseph Grohowski, founder and president of Praxis Technology. He developed Praxis’ titanium metal injection molding (MIM) process for manufacturing implant-grade titanium and mul- tiple technologies for porous titanium. Parts manufactured via titaniumMIMuse nearly 100%of themetal powder, offer- ing better material utilization, which translates to more cost savings. His talk included new heat treatment processes that greatly improve the performance of additively manu- factured titanium.
