    Abstract
  • 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.
