Shape memory effect and compositional dependence of Zr-Cu binary and Zr-Cu-Al ternary alloys

The intermetallic compound ZrCu experiences a transformation from a parent phase into a martensitic phase with rapid cooling. ZrCu possesses considerable promise as a high-temperature shape memory alloy. In the present study, the shape memory effects of ZrCu, which was formed in a Zr-Cu-Al ternary a...
