本文对不同成分(10 wt.％～50 wt.％Cu)钨铜合金现有的组织结构模型和理论物理性能参数计算模型进行了归纳总结,在此基础上推导了不同模型下的主要物理性能参数的理论值(包括密度,热容,热导率,电导率,热膨胀系数等).根据不同模型(体积混合物模型,German互联结构模型,Gasik微观力学模型)的特点进行了分析和比较,讨论了不同模型的适用范围,选取得到了不同成分钨铜合金的物理性能参数理论值,并与实验结果进行了比较,为钨铜合金的成分和性能设计与控制提供了初步的理论依据.%This paper studies the structure models and physical property models of W-Cu alloy with different content of Cu (10 wt.%-50 wt.%). Based on these models, the main physical property theoretical values (density, heat capacity, heat conductivity, specific conductance and heat expansion coefficient) are calculated. The comparison of characteristics of different models (capacity mixture, German's interconnect frame and Gasik' micro-mechanical model) are performed. The suitable theoretical values of W-Cu alloy with different content of Cu are selected and compared to the experimental values. The research offers the theoretical basis to design and control the constituent and property of W-Cu alloy.
