Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the examples, but not as the basis for any limitation on the invention.

[0016] Sponge titanium, pure aluminum, molybdenum-iron master alloy, and chrome-iron master alloy are prepared into titanium alloy according to weight percentage. The raw materials are uniformly mixed and then extruded into consumable electrodes for smelting. More than one smelting into ingot, melting vacuum degree 0-5Pa, arc voltage 30-40V, arc current 5000-10000A; after smelting, the ingot is prepared into a light ingot for forging by removing the shrinkage cavity and skin of the arc-receiving end; The chemical content is: Ti-(2.0~6.0)Al-(0.6~1.4)Mo-(0.6~1.4)Cr-(0.6~1.8)Fe, using multi-fire forging, and several times of pier forging for each fire The prepared forged slab adopts hot-rolling and cold-rolling processes to prepare titanium alloy plates for the top cover and bottom plate of the golf head.

Abstract

The invention relates to a low-cost forged titanium alloy material, a preparation method and application thereof. The material trademark of the titanium alloy is Ti-4Al-1Mo-1Cr-1Fe, and comprises thefollowing chemical components of, in percentage by weight, 2%-6% of Al, 0.6%-1.4% of Mo, 0.6%-1.4% of Cr, 0.6%-1.8% of Fe, and the balance Ti and inevitable impurities. During preparation, sponge titanium, pure aluminum, a ferro-molybdenum alloy and a ferro-chrome alloy are mixed according to the chemical composition ratio, then extruded into a consumable electrode for smelting, smelted into an ingot through a vacuum consumable electric arc furnace for more than two times, and forged to obtain the forged titanium alloy material. The Ti-4Al-1Mo-1Cr-1Fe titanium alloy has the advantages of low density, high strength, high plasticity, high elastic modulus, hot forging, hot rolling, cold forging and cold rolling process performance, and is suitable for a top cover and a bottom plate of a golfhead.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy materials, and in particular relates to a low-cost forged titanium alloy material, a preparation method and an application thereof. Background technique [0002] Titanium and titanium alloys have many advantages such as low density, high yield ratio, and corrosion resistance. They are known as "the third rising metal" and are an important strategic metal material that plays an important role in the construction and development of the national economy. With the gradual deepening of people's understanding of titanium knowledge, titanium and titanium alloys have been widely promoted and applied, especially the amount of titanium used in civilian industries such as sporting goods, construction, electric power, and automobiles has increased year by year. But high price has always been the biggest obstacle restricting the mass application of titanium alloys. Therefore, reducing the cost of mater...
