Method for preparing a titanium-aluminum alloy

Abstract

The present invention belongs to the field of titanium metallurgy, and particularly relates to a method for preparing a titanium-aluminum alloy. The technical problem to be solved by the present invention is to provide a method for preparing a titanium-aluminum alloy, including the following steps: a. adding TiCl4 and AlCl3 to a molten electrolyte in a protective atmosphere, wherein the molten electrolyte is a mixture of at least one of alkali metal chloride or alkaline earth metal chloride and alkali metal fluoride; b. electrolyzing the mixture obtained in step a; and c. obtaining a titanium-aluminum alloy through vacuum distillation of a cathode product after electrolysis. The method of the present invention can shorten the preparation process of a titanium-aluminum alloy and reduce the manufacturing cost thereof, which is of great significance to the development of titanium alloy in practice.
