N2 - The morphological change of substructures and the shape memory effect associated with the simple hexagonal B ARR LR beta -Sn structural transformation in Sn-(4. 2-5. 3) at% Cd alloys have been investigated. The alloys were quenched from a temperature at which the simple hexagonal structure was stable to various temperatures. Their substructures were observed by means of an optical microscope and their crystal structures were identified by means of an X-ray diffractometer. The massive transformation as well as the martensite one takes place as a diffusionless transformation. The massive transformation temperature (Ma) is independent of the solute content, while the martensite transformation temperature (Ms) decreases with increasing solute content. A shape memory effect was observed in Sn-Cd alloys and was remarkable for the specimen quenched below 160 K. The shape-recovery amount of the specimen, which is quenched below the Ms temperature and reveals a massive substructure, is considerably small.
