The stress relaxation characteristic and martensitic transformation of Fe-Mn-Si shape memory alloys under different deformation condition

摘要：

　　The stress relaxation characteristic and martensitic transformation in Fe-Mn-Si shape memory alloys under different deformation condition are studied by X-Ray Diffraction (XRD) analysis and TEM observation.The results show that the amount of stress induced e martensitic quickly increases when the suspending loading time below 10min (0~10min),and the increasing speed of ε martensitic gradually become slower when the suspending loading time above 10min.This is owing to the stabilization of stress induced ε martensitic.The stress relaxation ratio of Fe-17Mn-5Si-10Cr-5Ni and Fe-17Mn-5Si-2Cr-2Ni-1V alloys increase with increasing the suspending loading time,and the relaxation ratio of Fe-17Mn-5Si-2Cr-2Ni-1V alloy is obviously lower than that of Fe-17Mn-5 Si-10Cr-5Ni alloy.
