Effects of Heat Treatment and Deformation on 2H and 18R Martensites in Cu-9.97 % Al-4.62 % Mn Alloy

Abstract

In this study, some physical and mechanical properties of martensitic transformation in Cu-9.97 % Al-4.62 % Mn (wt%) alloy were investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM) and compression deformation test techniques. In SEM and XRD observations of Cu-9.97 % Al-4.62 % Mn alloy, two kinds of martensitic phases: thermally and deformation effect, and from DO3 parent phase, and the type of the produced martensite structures were noted.
