Notes:
The effect of aging temperature and aging time on properties of Cu-3.2Ni-0.75Si-0.3Znalloy were studied. The alloys were isochronally or isothermally aged after solution treatment. Thecold rolling prior to the aging treatment was used to increase the precipitation rate .The microstructureof the alloy was studied by means of transmission electron microscope (TEM). The results show thatthe fine and dispersed precipitates are fully coherent with the Cu matrix and make the alloy possesseshigher hardness and conductivity after the alloy was solution at 1173K and then aged at different time.The precipitates responsible for the age-hardening effect was Ni2Si.The transformation kinetics werestudied by analyzing the electrical resistance variation of the solution Cu-3.2Ni-0.75Si-0.3Zn alloy inthe process of aging
