Refractory alloys, although brittle and difficult to handle at room temperature, are amenable to bulk deformation processing at elevated temperatures. State-of-the-art hammer forging methods have been established to allow open and closed die forging of various refractory materials. Molybdenum alloys material are commonly produced into forged components. Current efforts on pure tungsten P/M material has resulted in methods to successfully produce thin wall 5 mm conical components. Pressed and sintered pure tungsten billets were deep drawn and back extruded under warm (1.370°C) and hot (2.200°C) forming temperatures. The forming methods and forging results will be outlined and discussed.
