Abstract

The invention discloses a preparation method of aluminium-vanadium-zirconium-molybdenum-chromium quinary alloy. The preparation method comprises the following steps of: (1) building a smelting furnace by adopting magnesite-chrome bricks; (2) drying the smelting furnace under the condition of 300-500 DEG C for 3-4 hours, and then cooling the dried smelting furnace to 50 DEG C or below for standby application; (3) preparing aluminium-vanadium-zirconium-molybdenum-chromium alloy from the following components in weight ratio: 12-16% of Al, 30-34% of V, 14-18% of Zr, 14-18% of Mo, and 22-26% of Cr; (4) igniting loaded furnace charges by magnesium powder for smelting to obtain an alloy ingot; (5) treating the smelted alloy ingot; (6) placing the treated alloy ingot in a vacuum induction melting furnace, and melting the alloy ingot into liquid; (7) performing pouring; (8) performing argon circulating cooling; and (9) performing crushing to obtain alloy particles of which the particle size is 1-6mm, and packaging the alloy particles. The preparation method has the beneficial effect that the prepared alloy has the advantages of being uniform in components, low in melting point, low in impurities, and high in purity. Through the adoption of the preparation method, needs for preparing TB9 type aeronautic titanium alloy are satisfied; the time for smelting titanium alloy is greatly shortened; and the production cost is reduced.
