Pseudoelastic effect ( ). (1) Elastic deformation of austenite; (2) austenite to single-variant martensite transformation (upper plateau); (3) elastic deformation of single-variant martensite; (4) elastic strain recovery; (5) single-variant martensite to austenite transformation (lower plateau). = single-variant martensite yield strain (i.e., maximum elastic strain). = single-variant martensite yield stress. = value of the stress component inducing transformation. = value of the stress component inducing transformation.
