Abstract:
A program for development of a high-temperature, liquid-phase sintered W alloy is being pursued. Th proved to be the most acceptable matrix base initial results indicate that W-Th alloys are capable of room-temperature deformation and workability, possess good high-temperature strength, and have a melting point in excess of 2000 C. Effort is concentrated on reducing or eliminating porosity to improve room-temperature fabricability. The decomposition of thorium hydride during sintering resulted in less porosity. A W-15Th alloy was initially found to have compressive ductility equivalent to W-20Th. The elevated temperature workability characteristics of these compositions have been initially determined at 1000 C, W-Th can be severely rolled or hammer-forged without occurrence of cracking.
