Problems solved by technology

Due to the low-interstitial elements O, N, C, and H impurity components of the vanadium-aluminum master alloy produced by the thermite method are difficult to control and the composition segregates, the quality of domestic high-β-type titanium alloys has not been able to reach the level of developed countries, and the performance gap is large.

Embodiment 1

[0036] Please refer to the attached figure 1 , the titanium alloy master alloy is smelted by ingot casting in the following order:

[0037] Step 1. Put the self-made vanadium furnace master alloy produced by the thermite method, super-0-grade sponge titanium, self-made titanium-tin alloy, and pure zirconium into the induction zone of the water-cooled copper crucible vacuum induction furnace, and then close the furnace door ;

[0038] Step 2, extracting the air in the water-cooled copper crucible vacuum induction furnace;

[0039] Step 3, start the power supply of the water-cooled copper crucible vacuum induction furnace, refine after melting in the water-cooled copper crucible vacuum induction furnace;

[0040] Step 4. Input the raw materials refined in Step 3 into the ingot mold to complete the ingot casting;

[0041] Step 5. After the belt furnace is cooled, break the vacuum;

[0042] Step 6: Take out the produced titanium alloy master alloy ingot, and store it for futur...

Embodiment 2

[0045] Please refer to the attached figure 2 , attached image 3 , the low-gap high-vanadium titanium alloy is produced by the steps in the following order:

[0046] Step 1. In a self-made vacuum welding box, the titanium alloy master alloy ingot and the TA0 bar of ultra-low interstitial elements are uniformly distributed in the axial and radial directions;

[0047] Step 2, using the plasma welding method to assemble and weld the vacuum consumable electrode of the primary ingot;

[0048] Step 3: Fix the welded self-consumable electrode on the vacuum consumable furnace, and carry out the first vacuum consumable ingot melting and casting according to the established melting process;

[0049] Step 4. After the first smelting ingot is completed, put the first smelting ingot into the vacuum welding box to assemble and weld the vacuum consumable electrode for the second smelting;

[0050] Step 5. Perform secondary vacuum self-consumption melting and casting on the welded seconda...

Abstract

The invention provides a manufacturing method of a low-gap high-vanadium-titanium alloy for sports equipment. The manufacturing method involves a titanium alloy mother alloy, pure titanium is added into the titanium alloy mother alloy, elements burnt by vacuum melting are supplemented, and the low-gap high-vanadium-titanium alloy is prepared after the structure and components are further adjusted. The manufacturing method mets high ductility and high tenacity, has very good cold and heat machining performance, and can meet the use performance of high strength and high elasticity.

Description

technical field [0001] The invention relates to the technical field of metal materials for sports equipment, in particular to a method for manufacturing a low-gap high-vanadium titanium alloy for sports equipment. Background technique [0002] In recent years, titanium alloys have been more and more widely used in the field of sports equipment. With their excellent performance and low specific gravity, titanium alloys can meet the manufacturing requirements of sports bicycles, skiing, skating, and mountaineering equipment. Especially in the production of golf equipment, titanium alloy is used in the manufacture of golf club heads, which has its unique advantages. [0003] Golf club heads are the core components of golf clubs, especially wood club heads, which require not only volume, but also better elasticity and impact toughness. The titanium alloy material used to manufacture the club head is increasingly difficult to manufacture. The commonly used titanium alloy grade ...
