Abstract

The phase transformation temperature and time of + 2 ß in Cu-Al alloy before and after 5Gpa pressure treatment were measured by differential scanning calorimeter, its activation energy and Avrami exponent were also calculated. The effect of 5Gpa pressure treatment on the phase transformation of + 2 ß in the alloy was discussed based on the measurement, calculation and the observation of alloy’s microstructure. The results show that 5Gpa pressure treatment can decrease the transformation temperature and transformation activation energy and shorten the transformation time, it is conducive to the phase transformation of + 2 ß in the Cu-Al alloy, but has little effect on the phase transformation mechanism.
