影响Mo-Cu合金电热性能的因素

Effect of various factors on the thermal and electric conductivity of Mo-Cu alloy

主要叙述了适用封接用Mo-Cu导热导电性能的测定方法，论述了Cu和Ni含量对钼铜合金热电性能的影响：机械活化处理及热处理等因素对钼铜合金热电性能的影响。认为Ni等少量杂质元素的加入，Mo-Cu合金材料的热电性能降低；机械活化处理使Mo-Cu合金的热导和导电性能下降；Cu含量的加入和适当的热处理使Mo-Cu合金的热电性能提高。

the test method of thermal and electric conductivity of Mo-Cu alloy for sealing materials, effect of Cu and Ni contents on the thermal and electric conductivity of Mo-Cu alloy, effect of mechanical alloying and heat treatment on the thermal and electric conductivity of Mo-Cu alloy has been discussed respectively in this paper. The results show that small amount element such as Ni can decrease the electric conductivity of Mo-Cu alloy; the thermal and electric conductivity of Mo-Cu alloy decreased after mechanical activation treatment of composite powders; the thermal and electric conductivity of Mo-Cu alloy increased with elevated Cu content and properly heat treatment.
