Abstract

Quantitative surface relief analysis proved that the incomplete shape recovery of a polycrystalline Fe-28Mn-6Si-5Cr alloy was not caused by slip deformation on loading but by irreversible phase transformation on heating, under given conditions ([54̄1̄] tensile axis, 5.9% strain). The observed area showed a higher recovery strain than the macroscopic recovery strain, implying inherently high reversibility. However, the value was significantly lower than that of a single crystal, due to the geometric constraint from surrounding grains, which reflected different transformation dislocations between forward and reverse transformations.
