Analysis Of Martensitic Transformation In Ni-Mn-Sn Fsma, Ajit Behera

Ajit Behera

Ferromagnetic shape memory alloys (FSMA) are a new class of potential multifunctional materials with advancement over the conventional heat-driven shape memory alloys due to their exceptional properties. FSMAs can be controlled by magnetic field have attracted considerable attention as a type of magnetic actuator materials. Among the Heusler alloys that exhibit magnetic shape memory effect, the most extensively studied are those of the Ni-Mn-Ga system. However, to overcome some of the problems related to practical application, such as the high cost of gallium and the low martensitic transformation temperature that they usually present, the search for Ga-free alloys has been …
