    摘要:

    W-Cu合金以其高的抗电弧烧蚀、抗熔焊性,高的导热导电性等广泛应用于冶金、材料、电子、军工和其他领域。电导率是其重要的性能指标之一,一直备受关注。本文对不同成分的钨铜合金现有的电导率计算模型进行了研究,对不同模型的特点和适用范围进行讨论,讨论了;推导了不同模型下的电导率,并与实验结果进行了比较。选取了合适的电导率理论值,并与实验值进行了比较。结果表明,低、高铜的区域理论值与实验值基本一致,提高铜含量和降低孔隙率可以提高W-Cu合金的电导率。这为钨铜合金的成分和电导性能设计提供了初步的理论依据。

    Abstract:

    W-Cu alloy has been applied in metallurgy, materials, electronics, military and other fields because it has good arc-resistance, anti-welding, conduct heatSandSelectricity and so on. Electrical conductivity is one of the important material performanceSindexes and has attractedSmuch attention. The electrical conductivity models of W-Cu alloy with different content of Cu are studied in this paper. The characteristics and applicableSrangesSofStheseSmodels is also discussed. The conductivity are calculated by using these models and compared with the experimental results and the theoretical values. The suitable theoretical values of W-Cu alloy are selected and compared to the experimental values. The results show the experimental conductivity is basically consistent with the theoretical values for W-Cu alloy with low or high Cu component. Enhancing copper content and reducing porosity lead to increasing the conductivity of W-Cu alloy. This offers the theoretical basis to design the constituent and electrical conductivity of W-Cu alloy.
