NiTi Shape Memory Materials
Abstract
Shape memory materials are broadly defined as materials capable of recovering large strains on demand. In this talk we will focus on processing-structure-property relationships in NiTi shape memory alloys. The talk will begin with a brief discussion of biomedical applications of NiTi in the cardiovascular and orthopedic spaces. Motivated by these applications, the talk will then cover the impact of thermo-mechanical processing on the structure and resulting monotonic and cyclic properties of NiTi. Following this, we will discuss the effect of composition changes on the behavior of NiTi, including the effects of ternary Pt addition. The talk will end with a discussion of both the topics we think we understand and those that we are certain we do not understand, which are the topics of future research efforts.
Bio
Professor Gall received his BS, MS, and PhD from the University of Illinois in Urbana Champaign in 1995, 1996, and 1998, respectively. His specific interests include metallic and polymer biomaterials, mechanically active materials, and nanometer scale materials and characterization. He has published over 125 journal articles and given over 185 professional talks. He has provided consulting on materials and engineering for law firms, industry, national labs, and the United States military. His research on shape memory alloys and polymers was the basis for founding MedShape Solutions, a company developing shape memory material based orthopedic devices.
Please join our speaker for light refreshments in 479 Watts Hall following the talk.
