    摘要:

    W-Cu合金以其高的抗電弧燒蝕、抗熔焊性，高的導熱導電性等廣泛應用于冶金、材料、電子、軍工和其他領(lǐng)域。電導率是其重要的性能指標之一，一直備受關(guān)注。本文對不同成分的鎢銅合金現(xiàn)有的電導率計算模型進行了研究，對不同模型的特點和適用范圍進行討論，討論了；推導了不同模型下的電導率，并與實驗結(jié)果進行了比較。選取了合適的電導率理論值，并與實驗值進行了比較。結(jié)果表明，低、高銅的區(qū)域理論值與實驗值基本一致，提高銅含量和降低孔隙率可以提高W-Cu合金的電導率。這為鎢銅合金的成分和電導性能設計提供了初步的理論依據(jù)。

    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.
