摘要
采用热常数测试仪测试了深冷处理前后Cu-Al合金在25～600℃的热扩散系数,通过对比深冷处理前后Cu-Al合金热扩散系数的变化,探讨了深冷处理对Cu-Al合金热扩散系数的影响。结果表明:深冷处理前后Cu-Al合金在25～600℃的热扩散系数变化趋势一致,深冷处理能增大Cu-Al合金热扩散系数,在400℃时,两者差值最大。
The thermal diffusion coefficient of Cu-Al alloy before and after cryogenic treatment in the heating temperature range of 25-600℃ was measured by thermal constant tester. The effects of cryogenic treatment on the thermal diffusion coefficient of the alloy were investigated through comparing the variation of the thermal diffusion coefficient before and after cryogenic treatment. The results show that the variation trend of the thermal diffusion coefficient of the alloy after cryogenic treatment is the same as before, cryogenic treatment can increase the thermal diffusion coefficient of Cu-Al alloy, and the maximum difference of the thermal diffusion coefficient before and after cryogenic treatment appears at 400 ℃.
