Nature of Phase Kinetics and Memory in Shape Memory Alloys

Shape Memory phenomenon in some intermetallics like NiTi is well known. However, during arbitrary thermomechanical loading, these materials exhibit several other interesting, yet less-understood phenomena. In this talk, Thermal Arrest Memory and associated effects during interrupted phase transformations in shape memory alloys are discussed and some fascinating underpinnings in the associated martensitic transformations are highlighted.
The research talk will be followed by a presentation by the speaker about potential Research and Teaching initiatives and future directions toward collaborative activities at the department. This will include a brief overview of the R&D experience of the speaker over 3 decades, and a strategy to pursue Research and Development of allied Aerospace technologies and engage with relevant organizations. A brief overview of proposed elective courses like Advanced Aerospace Materials, and Life-Cycle Analysis and Design of Aerospace systems and components is provided. These are aimed at enhancing the academic level of the students of the department and making them more contemporary.
