SCALE-UP DEVELOPMENT OF TANTALUM-BASE ALLOYS. Period Covered July 1, 1960 to September 30, 1961

OSTI ID:4830152

Melting and the effects of other processing variables on the quality and mechanical behavior of two selected tantalum-base alloys were studied. The two alloy compositions selected, Ta-10Hf-5W and Ta-30Nb -7.5V, were scaled up to 30- pound ingots and fabricated to sheet using conventional technique s of extruding, forging, and rolling. Mechanical-property data obtained from the sheet in various conditions of heat treatment and after various processing schedules show both alloys to possess good hightemperature strength as well as low-temperature ductility. Reproducibility of properties was also demonstrated. (auth)
