The properties of tungsten-rhenium alloys, obtained by compact sintering of dispersed powders which formed a tungsten-rhenium solid solution at relatively low temperatures, were investigated. Three systems were compared: a tungsten alloy with 2% rhenium, an alloy with dispersed additions of yttrium and hafnium oxides, and commercially pure tungsten. The properties included ductile-to-brittle transition temperature, bend strength, yield strength, and crack resistance. Structures were determined by scanning electron microscopy. Tungsten alloyed with small additions of rhenium possessed higher plasticity and in other mechanical properties was similar to cast and deformed alloys of the same composition.
