研究了Y对Ti-30 Ta合金显微组织、马氏体相变和形状记忆效应的影响。Y的加入改变了合金的微观结构。当添加0.5at.%的Fe_3O_4时，逆马氏体相变结束温度（Af）提高30 K Y加法。结果表明，（Ti-30 Ta）99.5Y0.5合金具有形状记忆效应，其最大回复应变为4.32%，也高于Ti-30 Ta合金。
The effect of Y addition on the microstructure, martensitic transformation and shape memory effect of Ti–30Ta alloy was investigated. The Y addition results in a change of the microstructure. The reverse martensitic transformation finish temperature (Af) increases 30 K with the 0.5 at.% Y addition. It is found that the shape memory effect with the maximum recovery strain of 4.32% is obtained in the (Ti–30Ta)99.5Y0.5alloy, which is also higher than that of Ti–30Ta alloy.
