摘　　要：分析了冷变形量和时效温度与时间等工艺参数对Cu Ni Si合金显微硬度和导电率的影响 ,同时研究了该合金的析出物结构。结果表明 ,冷变形可加速时效过程和提高时效效果 ,在 5 0 0℃时效 1h可使合金获得较佳综合性能。The effects of the cold rolling deformation and the aging temperature and time on microhardness and electric conductivity of Cu Ni Si alloy were studied and the construction of its precipitate was investigated.The results show that cold rolling will accelerate the aging process and enhance aging effect. The alloy reaches excellent comprehensive property when aging for 1h at 500℃.The microhardness and electric conductivity of the alloy lean mainly on the quantity,particle size and dispersion degree of the precipitate.
