The microstructure of a Cu-Zn alloy treated under different high pressures was investigated by means of metallographic,scanning electron microscope (SEM),energy dispersive spectrometer (EDS),and X-ray diffraction (XRD),and the hardness of the Cu-Zn alloy was also measured.The results show that the a phase with a smaller grain size,different shapes,and random distribution appears in the Cu-Zn alloy during the solid-state phase transformation generation in the temperature range of 25-750℃ and the pressure range of 0-6 GPa.The amount of residual α phase in the microstructure decreases and then increases with increasing pressure.Under a high pressure of 3 GPa,the least volume fraction of residual α phase was obtained,and under a high pressure of 6 GPa,the changes of the microstructure of the Cu-Zn alloy were not obvious.In addition,high pressure can increase the hardness of the Cu-Zn alloy,but it cannot generate any new phase.
