The effect of constant-strain aged and unaged on microstructure, martensite transformation, Curie temperature and magnetic field induction strain of Ni53Mn23.5Ga23.5ferromagnetic shape memory alloy was investigated in detail. The results show that reverse martensitic transformation temperatures of constant-strain aged sample slowly decrease, which martensitic transformation temperatures almost unchanged. In addition, Curie temperature of constant-strain aged sample is almost maintains consistent with solution-treated sample, but slowly increases saturation magnetization of constant-strain aged sample than solution-treated sample. Finally, the sample of constant-strain aged sample showed a larger magnetic field induction strain of 402 ppm.
