The paper analyzed the martensite transformation characteristic of Fe-Mn-Si alloy by XRD analysis and tensile test under different deformation condition. In this study, the amount of ε martensite of Fe-17Mn-5Si-10Cr-5Ni alloy was lower than that of Fe-17Mn-5Si-2Cr-2Ni-1V alloy under the same deformation condition, but the change rate of ε martensite was much higher than that of Fe-17Mn-5Si-2Cr-2Ni-1V alloy, and the stress relaxation rate of the both alloys increased with the increase of the stop loading time, and the relaxation rate of the Fe-17Mn-5Si-10Cr-5Ni alloy was obviously higher than that of Fe-17Mn-5Si-2Cr-2Ni-1V alloy.
