Grain growth in Cu-Zn-Al-Mn shape-memory alloy

The ordereddisordered phase transformation temperature and time of CuZn alloy before and after 2 GPa pressure treatment were measured by differential scanning calorimeter (DSC). The phase transformation activation energy and Avrami exponent were calculated and the effect of 2 GPa pressure treatment on the microstructure evolution was also discussed based on the kinetic parameters. The results show that 2 GPa pressure treatment on CuZn alloy from ordered (¢A) to disordered (¢) phase transformation shift to the low temperature region and can shortened the phase transformation time in the subsequent heating process, which is helpful to the formation of the microstructure with a fine grain size in CuZn alloy, but no new phase is generated.
