Abstract

The invention discloses a titanium alloy preparation method, and relates to the technical field of preparation methods of alloy materials. The method comprises the following steps that inert gas is used as a carrier gas to charge hydroborates into a furnace chamber; a titanium alloy is melted by a consutrode cold crucible, under the high pressure hydrogen atmosphere, borane is decomposed at the consutrode electrode tip to generate titanium boron, and parts of boron elements and hydrogen are fused into a titanium alloy melt body under the high arc temperature; and parts of boron elements fall on the surface of the melt body, and because the content of the boron elements decomposed by the gas is less, the boron elements are fused into the titanium alloy, the boron elements and hydrogen elements can refine the texture of the titanium alloy. By means of the titanium alloy preparation method, the texture of the titanium alloy can be refined, and the properties of the prepared titanium alloyare improved.

Description

technical field [0001] The invention relates to the technical field of preparation methods of alloy technology, in particular to a preparation method of titanium alloy. Background technique [0002] Boron is a good titanium alloy refiner. At present, people have widely used Ti-B alloy system to obtain high-performance titanium alloys, but the amount of boron should be well controlled, otherwise the damage tolerance value of titanium alloys will be seriously reduced. Hydrogen treatment of titanium alloys is an extremely excellent treatment method for titanium alloys. Hydrogen treatment can also improve the processing performance of titanium alloys, such as increasing the chip performance of titanium alloys during cold working, and can also increase the high-temperature deformation capacity of titanium alloys. At the same time, the microstructure of titanium alloys can be refined by removing hydrogen. The high-temperature dehydrogenation treatment of solid titanium alloys an...
