摘要

钨铜合金由于其具有良好的耐电弧烧蚀性、抗熔焊性、高导热导电性等特点,已被应用于冶金、材料、电子、军工等领域。电导率是重要的材料性能指标之一,一直备受大家关注。针对不同成分钨铜合金采用现有的电导率模型进行了归纳总结,并对不同模型的特点和应用进行了讨论,推导出不同模型下的钨铜合金理论电导率;并将合适的模型计算值与实验结果进行了比较。结果表明,低或高铜含量的W-Cu合金的实验电导率与理论值基本符合。提高铜含量和减少空孔隙可提高W-Cu合金的电导率。本研究可为钨铜合金的成分和电导性能设计提供理论依据。
        W-Cu alloy has been applied in metallurgy, materials, electronics, military and other fields because it has good arc-resistance, anti-welding, conduct heat and electricity and so on. Electrical conductivity is one of the important material performance indexes and has attracted much attention. The electrical conductivity models of W-Cu alloy with different content of Cu were studied in this paper. The characteristics and applicable ranges of these models were also discussed. The conductivity was calculated using these models and compared with the experimental results and theoretical values. The suitable theoretical values of W-Cu alloy were selected and compared to the experimental values. The results show that the experimental conductivity of the W-Cu alloy with low or high Cu component is basically consistent with the theoretical values. Increasing copper content and reducing porosity can increase the conductivity of W-Cu alloy. This offers a theoretical basis for designing the constituent and electrical conductivity of W-Cu alloy.
