【摘要】 采用冷等静压、真空烧结、挤压等粉末冶金技术成功制备了银铜钒合金,对其进行了化学成分、显微组织、物理性能分析,并与传统熔铸法制备的银铜钒合金进行了比较。研究结果表明,采用粉末冶金技术制备的银铜钒合金,其化学成分容易控制,显微组织中V的颗粒细小、分布均匀,力学性能优异。但合金中不可避免地存在少量的孔隙,导致电阻率偏高。更多还原

【Abstract】 AgCuV is made successfully by powder metallurgy technology including cold isostatic pressing,vacuum sintering and extrusion processing.The analysis of the chemical composition,the microstructure and the physical and mechanical properties had been done also.Then the properties were compared with the congener alloy prepared by the traditional casting method.The results show that there are several advantages of the AgCuV prepared by powder metallurgy technology:easier to control the chemical composition,fine particle and even distributions of V,excellent mechanical properties,but have higher specific resistance because of the holes existing in the alloys.更多还原
