Elastic properties of shape-memory alloys are of great importance because, among other factors, they determine movement of dislocations and thermoelastic phase-equilibrium phenomenon. This paper is concerned with the consideration of the elastic-modulus evolution at temperature-induced martensitic transformation compared with such at the shape-memory temperature cycle for NiTi, CuAlMn and TiZrHfCoNiCu shape-memory alloys.

Key words: martensitic transformation, elastic modulus, shape memory, internal friction, shape-memory alloys.
