Mechanical properties of high strength vanadium-base ternary alloys

High strength V-20wt.%Nb and V-10wt.%Ta base ternary alloys containing aluminium, chromium and molybdenum were studied. The fabricability and tensile properties at room temperature and in a temperature range 700–1000 °C were measured. The tensile strength values were estimated on the basis of the values for the corresponding vanadium-base binary alloys and compared with the experimental data. The estimated values are in good agreement with the experimental data. From these results, V-20wt.%Nb-5wt.%Al, V-20wt.%Nb-5wt.%Cr and V-20wt.%Nb 10wt.%Mo alloys were selected as alloys that could be recommended for their good high temperature mechanical properties.
