Abstract A moderate amount of g-phase precipitates in Ni-Fe-Ga ferromagnetic shape memory alloy can drastically improve its toughness. The martensitic transformation temperature, the microstructure and the crystal structure of the complicated alloys Ni50+xFe25-xGa25 (x=3, 4.5, 6) were investigated by DSC, XRD, SEM and TEM techniques. The results showed that the martensitic transformation temperature Tm went up along with the increasing Ni content; the Ni56Fe19Ga25 alloy exhibited a microstructure composed of fine and clear martensite lathes of several martensitic variants in different orientation. The 6M+14M mixed martensite and g-phases were detected in the Ni56Fe19Ga25 alloy by XRD and TEM. Among the investigated alloys, the Ni56Fe19Ga25 alloy had not only the most appropriate martensitic transformation temperature for practical application, but also the suitable crystal structure for facilitating the magnetostrictive strain.
