研究了时效对ＦｅＭｎＳｉＣｏＭｏ 合金的临界屈服应力、应力诱发马氏体逆转变以及形状记忆效应的影响． 结果表明，随着时效温度的升高，室温下的母相屈服应力与应力诱发马氏体相变临界应力之差增大，应力诱发马氏体逆转变温度Ａｓ 和Ａｆ 升高，而形状记忆效应在６００ ℃时效时出现峰值． 电镜组织观察表明，时效温度高于６００ ℃时，应力诱发马氏体中全位错密度增大，使应力诱发马氏体稳定性提高．
The effect of aging on the critical yield stress, stress-induced martensitic transformation and shape memory effect of FeMnSiCoMo alloy was studied. The results show that as the aging temperature increases, the difference between the yield stress and the critical stress induced by stress-induced martensitic transformation at room temperature increases, and the stress-induced reversal temperature As and Af of martensite increase. The shape memory The effect peaked at 600 ° C. Electron microscopy observation shows that when the aging temperature is higher than 600 ℃, the total dislocation density in stress-induced martensite increases, so that the stress-induced martensite stability improves.
