NiMnGa alloys have attracted extensive attention because their ferromagnetic characteristic provides an additional degree of freedom to control both the shape memory effect and the multi-stage phase transformations in this Heusler system. Technically, along with the large magnetic-field-induced strains… Contents 1 The
Ferromagnetic shape memory alloys (FSMAs) are a new class of active materials, which combine the properties of ferromagnetism with those of a diffusionless, reversible martensitic transformation. These materials are technologically interesting due to the possibility of inducing large shape changes with an
NiTi shape memory alloys are promising implant materials due to their shape memory effect and superelasticity. However, the high nickel content has hampered wider applications of the materials. Excessive surface corrosion and wear of NiTi raise health concerns because Ni ions released
