摘　　要：采用3批不同厂家的钨粉,通过烧结-熔渗法制备了钨渗铜材料,分析了材料的密度、金相组织和断口形貌,测试了不同温度下的拉伸强度,对比研究了高温钨渗铜材料的批次稳定性。结果表明:3个批次材料烧结性能一致,渗铜均匀性良好。组织相近,晶粒度相近,断口形貌相近,基本无差异;不同温度点的拉伸强度互有交叉,趋势一致,没有明显差异。对钨渗铜材料批生产过程中,原材料的供方选择和质量管控提出了方法和建议。Three batches of tungsten powder from different manufacturers were used to prepare copper infiltrated tungsten material by sintering-infiltration method.The density,metallographic structure and fracture morphology of the material were analyzed.The tensile strength at different temperatures was tested.The batch stability of high temperature copper infiltrated tungsten materials were comparatively studied.The results show that the three batches of materials have the same sintering performance and good uniformity of copper infiltration.The structure,the grain size and the fracture morphology are similar,and there is basically no difference.The tensile strength at different temperature points crosses each other and has a consistent trend without obvious difference.The methods and suggestions for raw material supplier selection and quality control in the batch production of tungsten copper infiltration materials are put forward.
