Abstract: A possible mechanism of all-round shape memory behaviour hy help of a physical model pro- posed by Muller has been ascertained.The all-round shape mernory effect can be due to the fact that stress induced martensite of two different orientations is formed during the martensitic transformation in the outer and inner layers of the specimen respectively.

Key words: all-round shape memory effect, stress induced martensitic transformation, Ti—51at.—%Ni, SMA
