Abstract

The mutual transformation of Martensite and Austensite and propagation of their interface are studied with the fourbeam moire interferometry during the process of loading of polycrystalline NiTi shape memory alloys (SMA). The distribution of Austensite and Martensite and the extension nearby the interface is observed from the moire photographs when the specimen is transformed.
