摘　　要：针对国内配气阀体易发生开裂问题,通过化学分析、显微组织观察及拉伸性能比较,介绍了国内外钼合金配气阀体材料的研究现状,对其成分、冶金方法和塑性成型等相关工艺进行了综合分析,提出了在真空熔炼方法基础上利用电子束提纯方法,通过挤压开坯和多步锻造等措施,能够满足工程试车要求,可以有效改善钼合金配气阀体的材料性能。Aiming at the crack problem in domestic pneumatic valves, both domestic and foreign molybdenum alloy pneumatic valves are compared in terms of chemical analysis, microstructure, and stretching performance. The compo- nents, metallurgies and plastic forming technologies of the molybdenum alloy in China and abroad are analyzed, and some improvement approaches are offered, such as adopting electron beam purification melting method after vacuum melting, and taking extrusive breakdown and multiple forging processes, which can meet the requirement of engineering test. These improvement approaches can improve the properties of molybdenum alloy for pneumatic valve.
