Abstract

The invention relates to the preparation of titanium alloy, in particular to aluminum-vanadium-molybdenum master alloy and the preparation method thereof. The alloy is composed of the following components calculated according to the weight percentage: V is 45 to 55 percent, Mo is 25 to 35 percent, and the residual is Al. The preparation process comprises the following steps: an outside-furnace ignition smelting method is adopted, the preparation is operated according to the conventional steps, the raw material drying temperature is 70 to 80 DEG C, the drying time is not less than 24 hours; the blending weight of the composition comprises that V2O5 is 1.00 kg, MoO2 is 0.39 to 0.47 kg, Al is 0.40 to 1.30 kg, CaF2 is 0.03 to 0.21 kg; the raw material charging temperature is 30 to 60 DEG C, the reaction is steady, and the alloy formation is good. The invention has the advantages that the invention is convenient for the preparation of the titanium alloy, the cost is low, and the alloying is even; the oxidation resistant performance is good, the alloy is easy to be stored and transported, and easy to be crushed.

Description

technical field [0001] The invention relates to the preparation of titanium alloys, in particular to an aluminum vanadium molybdenum (vanadium-based) master alloy used for the preparation of titanium alloys and a preparation method thereof. Background technique [0002] With the continuous development of titanium alloys, it is more and more necessary for the master alloy to be directly added to titanium for smelting, which avoids the cumbersomeness of simply adding metal elements separately, and the melting point of the vanadium-based master alloy is lower than the highest melting point of each metal element; The melting point of MoV alloy is 1860°C, while the melting point of Mo is 2610°C, which makes the preparation and melting process of titanium alloy stable, and avoids the phenomenon that the melting current applied fluctuates and is not easy to control due to the inconsistency of the melting point of the metal element. An existing aluminum-titanium rare earth compound ...
