摘　　要：【目的】解决钨渗铜复合材料中钨晶粒的异常生长和气孔等缺陷,提高钨铜合金的力学性能。【方法】对钨渗铜材料进行了热锻(HF)处理,研究了热锻处理对合金组织性能的影响。【结果】结果表明,热锻后钨渗铜复合材料孔隙减少,钨相和铜相的分布更加均匀,W-W邻接度降低,硬度由298 HV提升至338 HV,摩擦磨损系数由0.45降低至0.28。热锻温度为700℃时,钨渗铜复合材料拉伸性能最优,其室温抗拉性能度增长48.06%,高温抗拉强度显著提升。【结论】热锻能有效改善钨渗铜材料的组织,提高其力学性能。[Purposes]This paper aims to address the abnormal growth of tungsten grains and defects such as pores in tungsten infiltrated copper composite materials,and to improve the mechanical proper-ties of tungsten copper alloys.[Methods]Hot forging(HF)treatment was performed on tungsten infil-trated copper materials,and the influence of hot forging treatment on the alloy's microstructure and prop-erties was investigated.[Findings]The results showed that hot forging reduced the porosity of the tungsten-infiltrated copper composite material,resulting in a more even distribution of tungsten and cop-per phases.The W-W interconnection decreased,and the hardness increased from 298 HV to 338 HV.The friction coefficient decreased from 0.45 to 0.28.When the hot forging temperature was 700°C,the tensile properties of the tungsten-infiltrated copper composite material were optimized,with a 48.06%increase in room temperature tensile strength and a significant improvement in high temperature tensile strength.[Conclusions]Hot forging can effectively improve the structure of tungsten infiltrated copper materials and enhance their mechanical properties.
