Abstract

The invention provides an aluminum-niobium-tantalum intermediate alloy and a preparing method thereof and relates to the technical field of metal materials. The aluminum-niobium-tantalum intermediatealloy comprises, by mass, 8.0%-12.0% of Nb, 30.0%-34.0% of Ta and the balance Al. due to component and content control, the components of the aluminum-niobium-tantalum intermediate alloy are uniform,segregation is small, when the titanium alloy is smelted, titanium alloy component homogenization is facilitated, and component segregation is prevented. The preparing method of the aluminum-niobium-tantalum intermediate alloy is provided. The aluminum-niobium-tantalum intermediate alloy is prepared through a two-step method, namely the two steps of the thermit reaction and vacuum smelting are conducted. By means of the preparing method, homogenization stability of the components of the aluminum-niobium-tantalum intermediate alloy can be improved, the content of impurities of O, N and the likeis reduced, and the requirement for titanium alloy production can be better met.
