The Effect of Prior Parent Phase Cold Work on Martensite Transformation in Cu-Zn-Al Shape Memory Alloys.

Abstract

The effect of cold work upon the transformation kinetics of parent to martensite and martensite to parent was studied utilizing differential scanning calorimetry, x-ray diffraction, optical and transmission electron microscopy methods. Samples of a Cu-Zn-Al shape memory alloy were cold rolled above martensite start temperature to varying degrees of deformation. The cold worked samples displayed various deformation morphologies. The mechanisms by which these deformation morphologies were developed and the varying morphology crystallographic features were studied and characterized using x-ray diffraction and optical and transmission electron microscopy techniques. Keywords: Shape memory effect; Martensite transformation; Copper base alloys; Cold work; Theses.
