Abstract

Shape memory alloys (SMAs) belong to a class of shape memory materials (SMMs), which have the ability to 'memorise' or retain their previous form when subjected to certain stimulus such as thermo mechanical or magnetic variations. SMAs have drawn significant attention and interest in recent years in a broad range of commercial applications, due to their unique and superior properties. One such of those unique materials called Nitinol has been explained. Researchers have been carried out to evaluate the mechanical behaviour of Ni-Ti alloys, including their tensile, torsion and fatigue properties. The present work presents the phase transformations, elastic behaviour, properties and methods of manufacturing and training of Ni-Ti alloy of both Superelastic as well as thermally activated wires.
