中文摘要：
研究了时效温度及时效时间对Cu-3．2Ni-0．75Si-0．3Zn合金性能的影响。通过该合金在450℃时效过程中的导电率变化，根据导电率与新相的转变量之间的关系计算时效过程中新相转变比率。确定该温度下时效的相变动力学方程及导电率方程。同时研究了该合金在450℃时效不同时间后，经不同变形量后的再结晶组织和性能变化。结果表明：二次时效可使合金在较短的时效时间内获得更高的导电率。Cu-3．2Ni-0．75Si-0．3Zn合金经预时效＋变形后的时效过程中，可发生原位再结晶和不连续再结晶2种形式的再结晶。
英文摘要：
The effect of aging temperature and aging time on properties of Cu-3.2Ni-0.75Si-0.3Zn alloy were studied. The transformation ratio of new phase in Cu-3.2Ni-0.75Si-0.3Zn alloy was calculated when aging at 450℃ by measuring electrical conductivity, the relation between the electrical conductivity and the quantity of new phase. Both the equation of phase transformation kinetics and the electrical conductivity equation were obtained. The recrystallization microstructure and properties of Cu-3.2Ni-0.75Si-0.3Zn alloy after aging at 450℃ and different deformations were also studied. The results show that a higher electrical conductivity can be obtained by two-step aging treatment. The situ recrystallization and discontinuous recrystallization can take place in Cu-3.2Ni-0.75Si-0.3Zn alloy for the effects of pre-aging combined with after deformation-aging treatment.
