A brittleness test developed at the Los Alamos Scientific Laboratory (LASL) made it possible to quantitatively measure the limited ductility of sintered tungsten-base alloys. Subsequently, numerous Entered tungsten-molybdenum-rhenium compositions were evaluated to establish alloys which combined room-temperature ductility with a melting point above 2900°C. Ductility trends of the alloys were related to sintering temperature, molybdenum and rhenium content, and Th02 additive. The fusion temperatures of 18 alloys were de¬termined.
