Abstract
The martensite stabilization and rubber-like behavior (RLB) found a simple and general explanation by a recently proposed symmetry-conforming short range ordering (SC-SRO) mechanism (X. Ren, and K. Otsuka, Nature, vol.389, 579(1997). However, there exists another puzzling phenomenon called annihilation effect of martensite aging, which seems difficult to explain. It refers to that the martensite aging effect disappears, once the aged martensite experiences a reverse-transformation into the parent phase. This phenomenon has been ascribed to the faster diffusion in the parent phase, which removes the aging effect acquired during previous martensite aging In the present paper, we provided clear experimental evidence to show that diffusion in parent phase is not the major reason for this effect. Based on the SC-SRO mechanism of martensite aging, we showed that this phenomenon arises from a general feature of martensitic transformation, i.e., martensite twin pattern after a martensitic transformation cannot reproduce the twin pattern before the transformation.
