The following results were found: a magnetic fieldhigher than a critical one is needed to induce the martensitic transformation aboveM_s. The critical magnetic field increases with increasing temperature, and whenplotted against the temporature difference from M_s, it lies on a straight line notpassing through the origin. This result and thermodynamical analysis suggest thatpulsed magnetic field strongly promotes the athermal martensitic transformation andrestrains tht isothermal one. The influence of magnetic field on martensitic trans-formation in the present Fe-Ni-Mn alloy is mainly due to Zeeman effect. Theentropy change for athermal transformation at M_s, S_Ms~at is obtained to be 4.13J/mol.K. The amount of magnetic field-induced martensites increases linearly withthe maximum strength of pulsed magnetic field. Lath, plate and butterfly martensi-tes are formed under magnetic field.
