Abstract: The solid-state phase transformation microstructure of Cu-Zn alloy under different high pressure were investigated by means of SEM and XRD. The results show that the α phase with smaller grain size, different shape and random distribution apppears in the Cu-Zn alloy, when the solid-state phase transformation generation in the Cu-Zn alloy under 25~750℃ and 3~6GPa high pressure, and the volume fraction of transformation phase decreases with increasing pressure, under high pressure (6GPa), the changes of microstructure of Cu-Zn alloy is not obvious. In addition, the effect of high pressure on the solid-state phase transformation microstructure of Cu-Zn alloy was discussed.
