| 摘 要： | 对不同变形量的Cu-Ni-Si-Mg合金进行时效处理,研究了变形量、时效温度及时效时间对合金性能的影响。结果表明,时效前的预冷变形能够促进合金在时效过程中第二相的析出,从而提高合金的显微硬度和导电率。当合金经60%的冷变形,在450℃时效1 h,能获得较高的显微硬度与导电率,分别达到242 HV0.2和35.5%IACS。同时建立了该合金在450℃下,关于时效时间的相变动力学方程和导电率方程。 |

| Abstract: | The Cu-Ni-Si-Mg alloy was aged after varying cold deformation,the effect of cold deformation,aging temperature and aging time on microstructure and properties of the alloy were investigated.The results indicate that the cold rolling prior to the aging treatment can promote precipitation of second phase during aging and increase the hardness and electrical conductivity.The high hardness and electrical conductivity can be obtained after 60% cold deformation and then aged at 450 ℃ for 1 h,the microhardness and electronic conductivity are 242 HV0.2 and 35.5%IACS,respectively.Both the phase transformation kinetics equation and the electrical conductivity equation were established based on aging at 450 ℃. |
| Keywords: | Cu-Ni-Si-Mg alloy cold deformation aging electrical conductivity equation |
