摘要: ABSTRACT Martensitic transformations are diffusionless, displacive, and shear-like in nature. This being the case, they substantially influenced by an applied stress. Here, it is convenient to distinguish between stress-assisted strain-induced transformations. Many alloys which exhibit a thermoelastic type of martensitic transformation show shape memory effect, related phenomena such as two-way memory, supereiasticity martensite-to-martensite In these mode deformation martensite quite unusual. Certain orientations grow at expense others, resulting single crystal martensite, upon heating reverts its parent phase unique manner. These, other topics considered.
