Abstract

The transformation behavior of the shape memory alloy Ti _47.5Ni_47.5Cu₅ was studied. As for this alloy, Cu atom can take both the position of Ni atom and that of Ti atom. The alloy consists of a lot of base phase and a little of Cu-rich phase and Ti-rich phase. Under aging at 550°C for 5 hours, Cu content of base phase is higher and the amount of Cu-rich phase is less. The alloy transformation behavior also is also influenced by the heat treatment. When the alloy is treated at 850°C for 15 minute then quenched, it goes through the transformation of B2→B19'. When the alloy is aged at 550°C for 5 hour, it goes through two stage phase.
