Several alloys have been known to exhibit a mechanical shape memory effect associated with a thermoelastic martensitic-type phase transformation. Of particular interest is the alloy NiTi near the equiatomic composition. Experimental results are presented on the deformation modes in the early stages of 55.4 wt percent Ni (50.3 at. percent) alloy in a partially transformed state. Wires from this same batch of material have been put through more than 10/sup 7/ cycles of shape recovery in a new type of heat engine.
