HIGH ENERGY RATE FORGING OF COMMERCIALLY PURE TUNGSTEN AND TZM MOLYBDENUM ALLOY.
Abstract
A manufacturing methods study was conducted to determine the possibility of forging unwrought tungsten and molybdenum alloy by the high energy rate forging (HERF) method. Suc cessful HERF of unwrought refractory materials was found to be highly dependent upon the forging configuration and die design. Good forgings are possible when working stresses in the forged parts are compressive in nature. Tensile and shear stresses during forging generally result in fracturing of the billet if the refractory metals have received little or no plastic working prior to forging. Data for forging conditions and results of metallurgical examinations are presented. (Author)
