Structure and Mechanical Properties of Shape-Memory Alloys of the Ti – Ni – Cu System

  • Published:
Metal Science and Heat Treatment Aims and scope

The effect of copper additives in an amount of up to 35 at.% on the structure and phase transformations in ternary Ti – Ni – Cu alloys in conventional microcrystalline, submicrocrystalline and nanocrystalline states is studied. Complete diagrams of thermoelastic martensitic transformations B2↔B19′, B2↔B19↔B19′ and B2 ↔ B19 are plotted as a function of the copper content. Special features of variation of the microstructure are determined. Tensile mechanical properties including the parameters of the shape memory effect are measured.
