研究了时效对Ti48.8Ni50.8V0.4合金马氏体相变的影响。结果表明,固溶处理后的形状记忆合金的马氏体相变为典型的单阶段相变过程。在不同温度下时效0.5h的样品的相变温度均低于固溶处理的合金。随着时效温度的升高,相变温度升高。在500 °C下老化后,样品表现出多阶段转变。在500 ℃时效5 h以上的试样,冷却时发生A → R→M1和A → M2的相变,加热时发生M2 → A和M1 → A的相变。
In this article, the effect of aging on martensitic transformation of Ti48.8Ni50.8V0.4 alloy was investigated. The results show that the martensitic transformation of the solution-treated shape memory alloy is a typical single-stage transformation process. The transformation temperatures of the samples aged at different temperatures for 0.5 h were lower as compared to that of the solution-treated alloy. With the increase of aging temperature, the transformation temperatures increase. After aging at 500 °C, the samples exhibit a multiple-stage transformation. The samples after aging at 500 °C for more than 5 h resulted in the transformation sequence of A → R→M1 and A → M2 upon cooling and M2 → A and M1 → A upon heating.
