The invention relates to an
aluminium-
vanadium-carbon interalloy and a preparation method thereof. On the basis of producing an
aluminium-
vanadium interalloy in the prior aluminothermic method of reducing, the prior equipment and
smelting process are utilized, and the good-quality
aluminium-
vanadium-carbon interalloy can be produced by only adding a certain amount of carbon
powder. Through detection, the interalloy has uniform compositions without defects such as inclusions and the like, is added into a
titanium ingot to make carbon element added in a carbon-containing interalloy mode, eliminates the quality hidden troubles of
pollution and inclusions caused by directly using the carbon
powder in a
titanium ingot primary
smelting process, can effectively improve the uniformity and accurate control of the carbon element in a
titanium material, and solves the problems of addition and uniformity of the carbon element; and the produced titanium
ingot has even distribution of the carbon element, has no metallurgical defects such as the inclusions and the like, and can meet the quality requirement on a high-quality titanium material in the fields such as
aerospace and the like. The preparation method has the obvious advantages of simple process, simple and convenient operation, low cost, accurate composition control, stability and the like, and is suitable for industrial production.
