Method for preparing TB13 titanium alloy by using TC4 powder

The invention relates to the technical field of new materials, and particularly discloses a method for preparing TB13 titanium alloy by using TC4 powder, which comprises the following steps: selecting sponge titanium, vanadium-aluminum intermediate alloy and TC4 titanium alloy powder as raw materials; calculating the weight ratio of the sponge titanium to the vanadium-aluminum intermediate alloy to the TC4 titanium alloy powder according to the nominal composition of the TB13 titanium alloy, and weighing the sponge titanium, the vanadium-aluminum intermediate alloy and the TC4 titanium alloy powder according to the weight ratio; the sponge titanium, the vanadium-aluminum intermediate alloy and the TC4 titanium alloy powder are dried and then evenly mixed, and a mixture is obtained; preparing the mixture into an initial electrode of the consumable electrode vacuum furnace; and the initial electrode is repeatedly smelted for multiple times through a consumable electrode vacuum furnace to obtain the TB13 titaniu
