Abstract
The stress induced martensitic transformation stress and the yield stress of the Fe-28Mn-6Si-5Cr shape memory alloy under various temperature conditions were studied. From the result, the martensitic transformation stress increased by 1.0MPa/℃ with the increase of temperature. On the other hand, the yield stress decreased by -0.7MPa/°C for the temperature conditions from 80℃ to 280℃. While the stress induced martensitic transformation occurs in low stress rather than the slip in the region room temperature to 135℃, those critical stresses reverse at about 135℃.
