Abstract

The invention relates to the preparation of titanium alloy, more specifically an Al-Mo-Cr-Fe-Si intermediate alloy for titanium alloy preparation and process for preparing the same, wherein the constituents (by weight percent) of the alloy include, Al 11.4-35%, Cr 20-28%, Fe 6-10%, Si 4.0-5.6%, and balancing Mo. The preparing process comprises, employing furnace outside ignition smelting method, operating according to routine procedures, the raw material drying temperature being 70-80 deg. C, the drying time no less than 24 hours, calculated based on 1kg of MoO3, the charged mixture includes, CrO3 0.71-0.99kg, Fe 0.20-0.33kg, Si 0.046-0.065kg, Al 0.663-1.92kg, CaF2 0.05-0.4kg, the raw material shoving temperature being 30-60 deg. C.

Description

technical field [0001] The invention relates to the preparation of titanium alloys, in particular to an aluminum-molybdenum-chromium-iron-silicon (molybdenum-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 AlMoCrFeSi alloy is 1730°C, while the melting point of Mo is 2610°C, which makes the preparation and smelting 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-titani...
