Abstract
The invention provides a preparation method of vanadium aluminum titanium alloy, and relates to a preparation method of high vanadium titanium material. The preparation method of the vanadium aluminum titanium alloy is characterized in that the preparation process is that firstly, a metallothermic reduction method is adopted and aluminum is taken as a reducing agent to reduce vanadium pentoxide and titanium dioxide, so as to prepare one-step vanadium aluminum titanium alloy; and then the well-prepared one-step vanadium aluminum titanium alloy is crushed and secondarily refined in a vacuum medium frequency induction furnace, and the final product of the vanadium aluminum titanium alloy is obtained. According to the method provided by the invention, the metallothermic reduction method (one-step method) is adopted and the aluminum is taken as the reducing agent to prepare the vanadium aluminum titanium alloy, then the vanadium aluminum titanium alloy is melted in the vacuum induction melting furnace and crushed, and finally a product of the aluminum titanium alloy is obtained. By adopting the method, the problem of high oxygen content of traditional Al-V85 alloy is solved, and the vanadium aluminum titanium alloy with relatively low oxygen content is obtained through adding a titanium element while the proportion of aluminum to vanadium in the Al-V85 alloy is not changed, and the oxygen content of a titanium alloy ingot is successfully controlled.
Description
Technical field
A kind of preparation method of vanadium aluminum titanium alloy relates to a kind of high V-Ti preparation methods.
Background technology
High V-Ti such as Ti-4Al-22V, Ti-15V-3Al-3Cr-3Sn alloy possess excellent mechanical properties such as high-strength, high-ductility because of it, and are used widely in aerospace field, sports field, eyes industry.What domestic production was at present used is the Al-V85 alloy, but because of this alloy impurity amount is high, particularly oxygen element content is up to 0.20%, and the high V-Ti oxygen level that causes producing exceeds standard, and is difficult to satisfy the needs of high V-Ti product.
Summary of the invention
The object of the invention is exactly the deficiency that exists to above-mentioned prior art, and the vanadium aluminum titanium alloy preparation method of the Al-V85 alloy that a kind of alternative tradition uses is provided, the oxygen level that the solves high V-Ti problem that exceeds standard.
