dc.description.abstractFerromagnetic Shape Memory Alloys (FSMAs) exhibiting ferromagnetic martensites, emerge as new functional materials with interesting magneto-mechanical coupling effects such as the ferromagnetic shape memory effect. These classes of intelligent material, which can be significantly change their shape and dimensions under the application of external fields. Among them are the magnetostrictive alloys which in turn can be deformed by magnetic field (up to 0.1 percent) and shape memory alloys, which can be deformed by mechanical stress (up to 10 percent) in martensitic state. The deformations (up to 6 percent) under the action of the magnetic field can be obtained in materials, which undergo the thermoelastic transformation into ferromagnetic shape. It is well known that ferromagnetic shape memory alloy has diversified utilization, but not satisfactorily use, mainly because of high cost of processing and high cost of alloying elements. Among Heusler (Ni50Mn50-yX) (X= In, Sn, Sb) FSMA, Ni-Mn-Sn alloy have potential properties and exhibits lower cost. Martensitic transformation of Ni50Mn50-ySny (y= 5, 10, 12.5) alloys were investigated by differential scanning calorimetric measurement. It is observe that, by keeping weight percent of Ni, if we increase the weight percent of Sn; then martensitic starting temperature decreases.en
