SEM and X-ray diffraction studies on microstructures in Cu-26.04%Zn-4.01%Al alloy

Abstract

Due to fact that Cu-based alloys are very sensitive to the thermal treatments, in scanning electron microscopy and X-ray diffraction observations, according to the different quenching techniques Cu-26.04%Zn-4.01%Al alloys can display different product phases such as martensite and precipitation. Rapidly cooling sample was formed as M18R structure from the ordered DO3 phase and in the monoclinic case,β = 89.1 determined for sample. It was seen that a α-precipitation (fcc) phase in the matrix is slowly cooling.
