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 (A(f)) 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)(99.5)Y-0.5 alloy, which is also higher than that of Ti-30Ta alloy.
