Claim:
1. A method of forming a titanium base alloy powder, the method comprising: subsurface reduction of a chloride vapor with a molten alkali metal or molten alkaline earth metal to form reaction products comprising pre-alloy particles and a salt of the alkali metal or the alkaline earth metal, a majority of the pre-alloy particles having a composition of at least 50% by weight of titanium, 5.38% or more by weight of aluminum, and 3.45% or more by weight of vanadium, wherein the total amount of aluminum and vanadium is less than about 20% by weight; and recovering the pre-alloy particles from the reaction products to produce a titanium base alloy powder containing less than about 200 ppm alkali or alkaline earth metal and a surface area as determined by BET analysis of at least about 3 square meters per gram after distillation of the powder at temperatures between about 500° C. and about 575° C. for about 8 to about 12 hours.
