Vanadium-aluminum master alloys with small amounts of refractory metals such as ruthenium, are made substantially free of refractory inclusions and with a substantially homogeneous microstructure by reacting vanadium oxides with excess aluminum through an aluminothermic reduction reaction in the presence of the refractory to yield the desired master alloy. A preferred homogeneous vanadium-aluminum-ruthenium alloy without inclusions contains from about 59 to 70% of vanadium, about 29 to 40% of aluminum, and about 1 to 10% of ruthenium, all based on the weight of the alloy. The substantially homogeneous and inclusion-free master alloy is then used to produce titanium base alloys of higher quality, such as 4% vanadium and 6% aluminum titanium base alloys containing small amounts of refractory metals, usually containing from about 0.1 to 1.0% of ruthenium.
