Problems solved by technology

A variety of titanium and titanium alloys are also used in domestic daily necessities, sporting goods, engineering supplies and other fields. For example, in the domestic glasses market, various titanium alloys such as pure titanium and titanium nickel are used to manufacture spectacle frame components. The price is low, but it has the disadvantages of soft material and insufficient elasticity; titanium nickel has super elastic properties, but it is expensive and contains heavy metal elements harmful to human body - nickel
In the sporting goods market, the titanium alloy products currently used in golf heads have shortcomings such as insufficient elasticity of the hitting panel. In regular competitions, the golf ball cannot be hit high and far. At the same time, the high price restricts the widespread promotion of golf.

preparation example Construction

[0009] The preparation method of this type titanium alloy:

[0010] First, mix titanium sponge, aluminum vanadium alloy, aluminum beans or aluminum foil in a certain proportion to form an alloy material, press it into an electrode block with a hydraulic press, and then use a vacuum consumable arc melting furnace to melt it into an ingot for the second time, and then forge, Manufactured into forgings through grinding, heat treatment and other processing procedures; or manufactured into plates through forging, grinding, rolling, heat treatment and other processing procedures; or manufactured into bars, Wire, profiles; or manufactured into standard parts or components through forging, grinding, heat treatment, machining and other processing procedures.

[0011] state

Embodiment 1

[0013] Using grade 1 sponge titanium, aluminum vanadium 85 and aluminum beans as raw materials, according to the nominal composition of Ti-22V-4Al (wt%) for proportioning, after mixing, pressing into electrode blocks, and then welding the electrode blocks with argon arc Methods Welded into electrodes for smelting, smelted twice into ingots in a vacuum consumable arc melting furnace referring to the TC4 titanium alloy melting process, the weight percentage of the secondary ingot of titanium alloy was composed of: vanadium 22%, aluminum 4%, the balance for titanium. Use a hydraulic press or an air hammer to forge the ingot at 1050-1150°C, and then turn it into a Φ110mm round billet after repeated upsetting. Then precision forging is carried out below 950°C to become a round billet of Φ45mm. Finally, it is rolled into Φ8mm wire rod after machine peeling, grinding and repairing, and then ground or repaired to remove scale, and then rolled into Φ2mm wire rod through roller die dra...

Embodiment 2

[0015] Using grade 1 sponge titanium, aluminum vanadium 85 and aluminum beans as raw materials, according to the nominal composition of Ti-22V-4Al (wt%) for proportioning, after mixing, pressing into electrode blocks, and then welding the electrode blocks with argon arc Methods Welded into electrodes for smelting, smelted twice in a vacuum consumable arc melting furnace to form ingots, the weight percent composition of titanium alloy secondary ingots was: 22% vanadium, 4% aluminum, and the balance was titanium. Use a hydraulic press or an air hammer to forge the ingot at 1050-1150°C, and then turn it into a δ50mm square slab after repeated upsetting. Then rolling is carried out below 950° C. to form a slab of δ5 mm. Finally, after sandblasting, repairing, and pickling, the plate with the required thickness is cold-rolled, and after vacuum annealing or vacuum solution aging treatment, it becomes a finished plate for golf head hitting panels or other uses.

Abstract

The present invention relates to the components and preparation process of new type multipurpose beta-type titanium alloy with high strength, high elasticity, high plasticity, excellent cold machining performance, and good welding performance. The beta-type titanium alloy consists of V 20-23 wt% and Al 3.5-4.5 wt%, except Ti and inevitable impurity, including Fe not more than 1.0 wt%, C not more than 0.1 wt%, N2 not more than 0.05 wt%, and O2 not more than 0.02 wt%. The beta-type titanium alloy may be used in producing spectacle frame, golf club head or its hit panel, various elastic parts, standard parts, etc.

Description

technical field [0001] The invention relates to the composition and preparation method of a multipurpose beta-type titanium alloy with high strength, high elasticity, high plasticity, excellent cold workability, cold formability and weldability. Background technique [0002] Titanium alloy has high strength, high specific strength, excellent corrosion resistance and biocompatibility, and has been widely used in many fields of national economy and social life. A variety of titanium and titanium alloys are also used in domestic daily necessities, sporting goods, engineering supplies and other fields. For example, in the domestic glasses market, various titanium alloys such as pure titanium and titanium nickel are used to manufacture spectacle frame components. The price is low, but it has the disadvantages of soft material and insufficient elasticity; titanium-nickel has superelastic properties, but it is expensive and contains a heavy metal element harmful to the human body-n...
