Abstract
A polycrystalline Ni53.6Mn27.1Ga19.3 shape memory alloy was deformed in compression in four steps up to a final deformation of 3.0 % at room temperature. After each deformation step the relative elongation was measured in two thermal cycles in the temperature range 300 K to 640 K, where a thermoelastic martensitic phase transformation occurs.
A one-way shape memory effect and a two-way shape memory effect were observed after deformation of the alloy and their relation to other mechanical characteristics of the alloy are discussed.
