Problems solved by technology

SP-700 titanium alloy is widely used in the production of golf head hitting surface, because of its workability, strength, toughness, hitting feeling and cost, it is a titanium alloy with excellent balance for the ball head; SAT-2041 Titanium alloy is a new material that is widely used on the hitting surface of golf heads. It has excellent cold processing performance. After proper aging treatment, it can obtain high strength and high toughness, and has a good hitting feeling; Ti15333 and Ti1553 are the most widely used golf balls. Head hitting surface material, the strength and elasticity of the two materials are good, but the alloy contains element Zr, the cost is high, so it is not conducive to reducing the manufacturing cost of the golf head

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-(6.0~9.0)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 a titanium alloy plate for the hitting surface of a golf head.

Abstract

The invention relates to a high-strength high-elongation forged titanium alloy material, a preparation method and application thereof. The material trademark of the titanium alloy is Ti8Al-1Mo-1Cr-1Fe; the alloy comprises the following chemical components in percentage by weight of 6%-9% 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, the sponge titanium, the pure aluminum, the ferromolybdenum alloy and the ferrochromium alloy are mixed according to the chemical component proportion and then extruded into a consumable electrode for smelting, the consumable electrode is smelted into a cast ingot twice or more than twice through a vacuum consumable electric arc furnace, and then the forged titanium alloy material is obtained through forging. The Ti-8Al-1Mo-1Cr-1Fe titanium alloy has the advantages of lower density, high strength, plasticity, elasticity modulus, hot forging, hot rolling, cold forging and cold rolling process properties, and is suitable for the hitting surface of a golf club head.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy materials, and in particular relates to a high-strength and high-elongation 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, r...
