Description
Technical Field
The invention relates to a beta titanium alloy. The titanium alloy can be used as a spectacle frame and can also be used in other fields, such as the fields of medical treatment, sports goods and the like.
Background
The metal materials currently used for manufacturing spectacle frames are mainly the following: zinc copper white, monel and nickel alloys, pure titanium and beta titanium alloys, titanium nickel shape memory alloys, noble metals, and the like. The zinc-copper-nickel spectacle frame is the metal spectacle frame with the lowest price, but because of poor corrosion resistance, green patina is easily formed, and the appearance is influenced. Monel (containing copper, zinc and nickel) and nickel alloy have good processing performance, and spectacle frames made of Monel have many styles and are popular with teenagers, but the Monel and nickel alloy have poor corrosion resistance. Studies have shown that nickel ions in the free state tend to cause skin irritation, and europe and the united states have suggested that customers do not wear such frames. Precious metal frames are expensive and difficult for the average consumer to withstand. Pure titanium, beta titanium alloy and titanium-nickel shape memory alloy have good corrosion resistance and light weight, and most of the traditional middle-grade and high-grade metal spectacle frames are made of three materials. The titanium-nickel shape memory alloy has the difficult problem of welding, so that the spectacle frame made of the titanium-nickel shape memory alloy has a single style. The spectacle frame made of pure titanium is popular among consumers due to the characteristics of light weight (48-60% of the weight of a common nickel-based alloy spectacle frame), high strength, corrosion resistance, easy surface coloring, attractive appearance, durability and the like. But pure titanium has a relatively high young's modulus (about 120 GPa). The glasses frame made of the elastic rubber has insufficient elasticity of the glasses legs, and the glasses legs need to be adjusted due to the relaxation of stress after the glasses are worn for a period of time. The beta titanium alloy has all the advantages of the pure titanium, the spectacle frame made of the beta titanium alloy makes up the defect of the elasticity of the spectacle legs of the pure titanium spectacle frame, and the spectacle frame made of the beta titanium alloy has more styles due to excellent processing performance and excellent welding performance, so that the spectacle frame made of the beta titanium alloy is used as a middle-grade or high-grade ornament and a fashion in developed countries such as Europe and America.
After the solid solution beta titanium alloy is cold-processed, the strength is increased due to work hardening, but the elastic modulus still remains at the level of the solid solution state, and the elastic property of the material is greatly improved. Therefore, the beta titanium alloy spectacle accessory is generally processed by solution treatment and then is processed into a finished product by cold machining, so that the elastic property and the surface quality of the accessory are ensured. At present, the beta titanium alloy used for manufacturing spectacle frames mainly comprises Ti-4Al-22V, beta III, beta c and the like, but the beta titanium alloys have solid solution Young modulus of about 85GPa, cold working rate of about 80 percent and solid solution strength of 800-900 MPa. The elastic modulus of the solid solution beta titanium alloy is reduced, and the cold processing rate of the material is improved, so that spectacle accessories manufacturers can produce more spectacle accessories with good styles and elasticity. The proper reduction of the strength of the solid solution beta titanium alloy can improve the service life of the accessory production die.
U.S. patent document US6607693B1 reports that the titanium alloy contains 30-60 wt% of vanadium group elements, the young modulus can reach 75GPa or even lower, and the tensile elastic limit is more than 700MPa, and provides a preparation method thereof.
U.S. Pat. No. 5, 6419358B1 reports a pseudoelastic β titanium alloy for spectacle frames, which comprises the following chemical components: 10 to 12 percent of molybdenum, 2.8 to 4.0 percent of aluminum, 0 to 4 percent of niobium and 0 to 2 percent of chromium and vanadium. The elastic recovery of the alloy can reach 3.5%. The cold workability of the alloy is not mentioned in the literature.
U.S. patent document 5509933 reports the use of titanium alloys for hot working with good biocompatibility, high strength, and low young's modulus. The alloy comprises the following components in percentage by weight: zirconium less than 20%, niobium 10-20% or 35-50%. The properties given here are only Ti-13Nb-13Zr.
In the united states patent document 5871595, a medical titanium alloy with low elastic modulus and good biocompatibility is reported, and the chemical composition range is as follows: 2.5 to 13 percent of zirconium, 20 to 40 percent of niobium and 4.5 to 25 percent of tantalum, wherein the total weight of the niobium and the tantalum is 35 to 52 percent, and the weight ratio of the niobium to the tantalum is 2 to 13.

Detailed Description
Example one
Commercially available titanium sponge, zirconium iodide, niobium bars and hafnium sponge were prepared into single electrodes of size □ × 150 × 400, which were assembled in a vacuum welding chamber to form consumable electrodes. The first and third smelting are carried out in a vacuum consumable electrode furnace, and the second smelting is carried out in a vacuum shell type furnace. The vacuum degree of the third smelting is not more than 5Pa. The current of the third smelting is 9000A, 13000A and 11000A in sequence. The cast ingot is prepared into a wire drawing wire blank with the diameter phi of 8.0 through the procedures of cogging, forging, rolling and the like by adopting the traditional processing technology of titanium alloy. The surface of the wire drawing billet is subjected to solution treatment at 800 ℃/10 min/air cooling in a tube furnace after being cleaned by surface defects, and an oxide film formed on the surface of the wire drawing billet after the solution treatment can be used as a carrier of a wire drawing lubricant. After the graphite emulsion is coated on the surface of the wire blank and dried, the metal-based stearic acid (wire drawing soap) is coated on the surface of the wire blank, and then cold drawing can be carried out, wherein the single-pass processing deformation of the cold drawing is controlled to be about 15%. After 3-4 passes of drawing, the solid solution treatment and the coating of the graphite emulsion and the metal-based stearic acid are repeated, and then the next cold drawing process is carried out until the diameter of the wire is drawn to phi 4.25. Straightening and solid solution treatment are synchronously carried out on the wire with the diameter of 4.25 on a tension electric heating straightening machine, the heating current is controlled to ensure that the heating temperature of the wire does not exceed 800 ℃, and the treatment time is 1 minute. The straightened wire needs to be ground on a centerless grinding machine to remove an oxide layer on the surface, the grinding amount is 0.25 mm, and a finished wire with a bright surface and no surface defects is obtained.
