中文摘要	In this work, Ni(55)Fe(18)Ga(27) ferromagnetic shape memory alloy was prepared through a suck-casting method. The effects of annealing and heating/cooling rate on the martensitic transformation temperatures were investigated by differential scanning calorimetry (DSC). The results showed that the phase transformation temperatures increase with increasing the annealing temperature, upon the heating and cooling process. However, the start and the finish temperatures (M(s) and M(f)) of martensitic phase transformation increased firstly and then decreased upon the cooling process with the increase the annealing time at 300 degrees C. The start and the finish temperatures (A(s) and A(f)) of inverse phase transformation increased slightly upon the heating process with the increase of the annealing time. The results can be explained by the evolution of the microstructure after heat treatment. It was also found that the phase temperatures show great dependence on the heating/cooling rate of the DSC test, A, and At increased and Ms and Mf decreased with the increase of the heating/cooling rate.
