| Abstract | Detailed crystallographic analysis was carried out on the martensitic transformation and the various variant combinations in 18R martensite in a Cu-Zn-Al alloy. The self-accommodation of martensitic shear strain is quite perfect within a variant group, but not effective or even does not exist for variant combinations which belong to different groups. Twenty-three unique variant combinations between 24 martensite variants can be divided into four groups, i.e. reflection twin, 180 degrees rotation twin, 120 degrees rotation twin and 90 degrees rotation twin. TEM and HREM observations show that the A/C boundary is straight, well-defined and perfectly coherent, the A/B boundary is irrational, coherent and gradually curved, and the A/D boundary is stepped. The A/C and A/B boundaries have obvious mobility, and the mobility is not effective for AID boundary. The interplate group boundaries are curved, blurred and immobile. The morphology, structure and mobility of interplate boundary are ail related to the degree of self-accommodation and the misorientation of twin boundary. (C) 1999 Acta Metallurgica Inc.
