BIOMED Special Seminar
Title:
Shape Memory Alloy Research at the Indian Institute of Technology (IIT) – Madras, India

Abstract:
Shape memory alloys (SMAs) possess the functional properties of shape memory and superelastic effects. They are therefore used in many engineering and biomedical applications. In the field of medicine, it is mostly Ni-Ti shape memory alloys that have been used because of their corrosion resistance and biocompatibility. But these alloys are difficult to produce and process and are also very expensive. In addition, even till date there is still some controversy raging over the deleterious influence of Ni on the human body from in vivo medical devices based on Ni-Ti SMAs.
More recently, efforts have been made to develop SMAs, such as Fe-based and Cu-based, Ti-based (Ni-less), that are easier to produce and process, and are also less expensive. But these SMAs possess less corrosion resistance and poor compatibility. Studies are therefore made to increase their suitability for biomedical applications through compositional and microstuctural modifications.
At IIT-Madras, SMA research includes alloys such as Ni-Ti, Ni-Ti-Cu, Ni-Ti-Zr, Ni-Ti-Ag, Cu-Zn-Al, Cu-Al-Mn, Cu-Al-Fe, Cu-Al-Ni, Fe-Mn-Si, Fe-Ni-Co, etc. An overview of the research efforts will be presented in this talk.
