Abstract

In Part I of this study [1], group theory is used to describe the morphology and microstructure (including the orientation relationships among lattice correspondence variants, habit plane variants and the self-accommodation diamond) of 2H martensite in shape memory alloys (SMAs). The microstructure of the habit and twinning planes and the orientation relationships among the lattice correspondence variants, habit plane variants, and self-accommodation plate groups are naturally categorized by means of group theory. In this study, the method developed in Part I [1] is used to study phase transformation from DO3 austenite to 2H martensite in Cu-14.2Al-4.3Ni (wt%) shape memory alloy. The morphology and microstructure of this kind of martensite are demonstrated by graphic visualization.
