Abstract

The invention relates to a Ti-Al series intermetallic compound alloy which is smelted from a raw material containing titanium in the Panxi area. Per 100Kg of the raw material containing titanium of the Panxi area contains the following auxiliary materials: 75-115Kg of metallic aluminum, 15-25Kg of calcareous metallurgical auxiliary material, 18-28Kg of potassium chlorate and 1.5-3.5Kg of calcium-sodium series treating agent and can also contain any one or a combination of the following two auxiliary materials: 3-10Kg of vanadium series raw material, 12-45Kg of columbium series raw material, 4-6Kg of carbon raw material or 3-4Kg of silicon raw material. The invention has stable raw material source and safe and reliable production process, and a prepared Ti-Al series intermetallic compound alloy product has stable product quality and can meet the technology and quality requirements on Ti-Al series intermetallic compounds of the modern industry. Meanwhile, the invention also solves the technical problem of smelting the Ti-Al series intermetallic compound alloy product by using a vanadium-titanium raw material with a high impurity content of the Panxi area, thereby rewriting the history that the raw material containing titanium of the Panxi area cannot be used for producing titanium alloy because of the high impurity content and filling a domestic blank.

Description
