摘要
采用正交试验对Cu-3.2Ni-0.75Si-0.3Zn合金的时效工艺进行了研究。结果发现,各因素对合金导电率和显微硬度影响程度的主次顺序分别为:时效温度>合金状态>时效后冷变形量>时效时间和时效温度>冷变形量>合金状态>时效时间。在保证合金性能不降低的情况下,该合金热轧板材经60%冷变形后,可直接进行时效而省去固溶处理。合金经最佳工艺时效和60%冷变形后,导电率和显微硬度分别可达41.96%I-ACS和263.4Hv。
Influence of technological factors on the aging of Cu-3.2Ni-0.75Si-0.3Zn alloy was investigated with orthogonal test. It was founded that the sequence affecting electric conductivity and micro-hardness is as follows, aging ternperature〉alloy＇ s state〉 degree of cold deformation〉aging time and aging temperature〉 degree of cold deformation〉 alloy＇ s state 〉 aging time. The alloy can be direct aged after 60% cold deformation without solution and the properties will not be deteriorated. Mter proper aging and 60 % cold deformation, the electric conductivity of the alloy reaches 41.96 % IACS and the micro-hardness reaches 263.4Hr.
