Mechanical properties of vanadium-base binary alloys

The fabricability and tensile properties of solid-solution-strengthened vanadium-base binary alloys containing aluminium, titanium, niobium, tantalum, chromium, molybdenum or iron were studied. The alloys were prepared by non-consumable arc melting and contained 150-370 ppm O, 20-250 ppm N and 40-130 ppm C. The V-Ti, V-Nb and V-Ta alloys were superior to the other alloys in their fabricabilities into sheet. The tensile properties were examined between room temperature and 10000C. The tensile strength values of the V-Nb and the V-Ta alloys were higher than those of the V-Al and the V-Cr alloys. The tensile strengths of the V-Al, V-Cr and V-Mo alloys increased in proportion to the increase in atomic per cent of alloying element, while those of the V-Nb, V-Ta and V-Fe alloys increased with the square root of the atomic per cent of the alloying element.
