| Abstract: | 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 recently attempted. This paper aims to represent the behavior
of Ga free Ni-Mn-Sn Heusler FSMA by varying the weight percentage of Sn. Three alloys i.e.
Mn50Ni50-xSnx (x = 5, 7.5, and 10) were produced as bulk polycrystalline ingots by arc melting.
The structural austenite-martensite transformation was che... |
