Abstract
Arc-melting and powder metallurgy techniques are used to incorporate fine, refractory dispersants in vanadium-columbium base alloys in order to improve their long-time, elevated-temperature strength properties. Solution annealing and aging studies of arc-melted alloys containing hafnium or zirconium in combination with carbon indicate that the hafnium carbide phase is more stable. The hydride process was used to obtain powders of V-60w/o Cb-1w/o Ti, to which fine oxide or carbide powders were added. After blending, cold- compacting, sintering at 2800 F, and annealing at 2000 and 2400 F, specimens containing alumina and thoria exhibited a high degree of reactivity with the alloy base. Improved stability was noted in the alloys containing ceria, lanthana, yttria, hafnium carbide, and zirconium carbide.
