Shape Memory Alloys: Current Status and Future Prospect for industry
Ibrahim Karaman - Raymundo Arroyave, Texas A&M University

Shape Memory Alloys (SMAs) are unique class of structural and functional materials because of their unique ability to change their shape upon the application of external effects such as stress, heat, and magnetic field and recoverability of the shape change upon removal of these effects. Even though, they were invented in 60’s, in the last ten years, there is an ever increasing interest on several aspects of SMAs pushing its limits for new applications, for example in space, energy exploration, defense, and biomedical applications, in MEMS and NEMS in the form of thin films, nanowires, porous state etc. which has in turn led to the development of new alloys such as magnetic SMAs, high temperature SMAs, Ni free biomedical SMAs, and inexpensive iron-based SMAs.

In this talk, current research activities at Texas A&M University in magnetic SMAs, high temperature SMAs, Ni-free SMAs and developing inexpensive SMAs will be presented. Recent findings in magnetic SMAs will be discussed. Possible applications for high temperature SMAs, iron-based SMAs and magnetic SMAs will be introduced especially for aerospace and energy exploration industries.

Bio: Ibrahim Karaman

Ibrahim Karaman received his Ph.D. from University of Illinois at Urbana-Champaign in 2000.  He joined the faculty of Department of Mechanical Engineering at Texas A&M University in 2000. Currently, he is The Dietz Career Development Associate Professor in the same department. He is also a member of the Faculty of Materials Science and Engineering Interdisciplinary Graduate Program. His main research interests are processing-microstructure-mechanical/functional property relationships in metallic materials including 1) ultrafine and nanocrystalline materials, and 2) conventional, high temperature and magnetic shape memory alloys; micro-mechanical constitutive modeling of crystal plasticity; twinning and martensitic phase transformation in metallic materials.

Dr. Karaman received several national and international awards including the National Science Foundation CAREER Award in 2002, Office of Naval Research Young Investigator Award in 2005, The Robert Lansing Hardy Award from The Minerals, Metals and Materials Society (TMS) in 2005, an Honorable Mention for the Early Career Faculty Fellow Award from TMS in 2007, and Gary Anderson Early Achievement Award from the ASME and AIAA joint committee on adaptive structures. He is an author or co-author on more than 80 refereed journal articles.
