Abstract
The influence of copper doping (25 at. %) upon the structural and phase transformations of triple alloys of the TiNi–TiCu quasi-binary cut is studied by transmission and scanning electron microscopy and electron and X-ray diffraction. A generalized complete diagram of B2 ↔ B19′, B2 ↔ B19 ↔ B19′, and B2 ↔ B19 thermoelastic transformations proceeding upon cooling as the copper content increases in the intervals of 0–8, 8–15, and 15–25 at. %, respectively, is constructed. Specificities of changes in the mechanical properties and microstructure of B19 and B19′ martensites in relation to copper doping are studied.
