摘要：

The deformation behavior and morphology of martensite in Ni-Al alloys have been studied by means of compression tests, optical microscopy, and transmission electron microscopy. Martensite deformation modes were investigated by examining microstructure changes upon compression. The shape memory effect is quantified by studying the incremental strain by compression testing below the M(f) temperature and measuring the shape recovery in a high-temperature dilatometer. The martensite features internal twins, and the twin plane is determined as {111}fct. The magnitude of the lattice invariant shear (by twinning) is determined by measuring the relative thickness of twin pairs and is 0. 128.
