中文摘要：
研究时效温度和时间对Cu-1．0Ni-0．25Si-0．1Zn合金组织和性能的影响，以及冷变形对该合金时效后性能的影响。合金经850℃固溶、450℃时效处理后，第二相呈弥散分布，并可获得较高的显微硬度及导电率。通过该合金在450℃时效过程中的导电率变化和根据导电率与新相的转变量之间的关系计算出了时效过程中新相的转变比率。从而确定了该温度下时效的Avrami相变动力学方程及导电率方程。
英文摘要：
The effect of aging temperature and cold deformation on microstructure and properties of Cu-1.0Ni-0.25Si-0.1Zn alloy were studied. The secondary phase was dispersive distribution in the alloy, the high hardness and electrical conductivity were obtained after the alloy was solution at 850 ℃ and then aged at 450℃. The transformation ratio of new phase in the 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 Avrami phase transformation kinetics and the electrical conductivity equation were obtained.
