Abstract:

Samples of martensitic Cu-Zn-Al shape memory alloy were deformed by cold rolling below MI martensite finish temperature. The effect of cold work upon the reaction kinetics of parent to product and product to parent transformations was studied utilizing differential scanning calorimetry methods. Characterization of the microstructure of selectively deformed shape memory alloy samples was accomplished by optical and transmission electron microscopy techniques. Correlation of microstructure and substructural conditions with associated transformation trends provided an understanding of the effect of cold work, as characterized by stress induced morphology, upon shape memory behavior.
