Shape‐memory phenomena

APR 01, 1984
The martensite transformation, first noticed in steels in the nineteenth century, gives materials properties that depend on their histories and that allow them to recover earlier shapes after apparently plastic deformation.

If you deform an ordinary material below its elastic limit and keep it below its annealing temperature, it will return to its original shape once the load is removed. If the stress is too large, however, or if the temperature is allowed to become too high, the deformation becomes permanent, and the material retains no memory of its original shape.
