Effect of Deformation on the Transformation Temperatures of Martensite and Bainite Structures in Cu-9.97%Al-4.62%Mn Alloy

Abstract

At present study of Cu-9.97%Al-4.62%Mn alloy system is used. Some physical properties of martensitic and bainite phase transformatios in Cu-9.97%Al-4.62%Mn (wt%) alloy were investigated by means of scanning electron microscopy and differential scanning calorimetry. In scanning electron microscope observations of Cu-9.97%Al-4.62%Mn alloy were noted two kinds of martensitic phases. These phases were defined as β 1 (M18R) and γ 1 (2H) martensites structures. According to differential scanning calorimetry measurement results, the deformation induced temperature is expected to be higher than the thermally induced temperature in Cu-9.97%Al-4.62%Mn alloy for martensite and bainite structures.
