Research on high temperature forming properties of TC4 titanium alloy plate and strip

Titanium metal has the advantages of light weight, high strength, corrosion resistance and good high temperature performance. It has important application value and broad application prospects, so it is called the "third metal" and the "metal of the 21st century".

Plate and strip are the main products of titanium processing materials, accounting for more than 60% of the consumption of titanium processing materials. They are mainly used in national defense, military industry, aerospace, petrochemical industry, salt and alkali production, metallurgy, shipbuilding, seaside power stations and medical and Sports and other industries. With the development of the economy and the advancement of science and technology, the market demand for titanium plates and strips is also increasing rapidly. This has brought opportunities to the development of titanium plate and strip processing technology and equipment, but at the same time it has also affected the mechanics of the product. Performance, dimensional tolerance, surface quality and cost-effectiveness have put forward higher requirements [3-8].

Compared with steel, copper, aluminum and other metal plates and strips, titanium plates and strips are new high-strength, lightweight materials with high-end application fields and promising development prospects. However, their production technology requirements are high and the process is difficult, which is especially reflected in It has high hot rolling deformation resistance, large degree of work hardening, and narrow thermal deformation temperature range. Grade 5 Ti-6Al-4V Titanium Foil / titanium block / Gr12 Ti-0.3Mo-0.8Ni Titanium Sheet

(1) The crystal structure of titanium is hcp (hexagonal close-packed), and its mechanical properties show significant anisotropy. There are only three slip planes (basal plane, pyramid plane, prism plane) and one slip direction at room temperature. (Titanium has two isomorphous crystals: α titanium with hcp structure below 882 ℃, and β titanium with bcc (body-centered cubic) structure above 882 ℃).

(2) Titanium has a strong affinity with oxygen at high temperatures, and oxygen elements continue to diffuse into the matrix, forming a hard and brittle interior of titanium that reduces its plasticity. In addition, when heated in a reducing atmosphere, titanium has a particularly strong hydrogen absorption effect. This effect It will cause hydrogen to diffuse into the metal and reduce its plasticity.

Due to the above reasons, the hot rolling process of titanium plates and strips and processing equipment such as hot rolling mills need to be specially developed and designed according to their characteristics, and the design must be based on accurate material performance parameters and other data, such as the temperature and strain rate of titanium at different temperatures and strain rates. Yield strength under high temperature, thermal conductivity at high temperature, thermal radiation coefficient, chemical composition and thickness of surface oxide scale, stress strain curve characteristics, etc.

What is the high temperature resistance of titanium alloy seamless pipes?

Titanium alloy seamless pipe is a pipe material with good high temperature resistance. It is a low-density and high-strength metal material with excellent oxidation resistance, high temperature resistance and corrosion resistance, and is especially suitable for use in high temperature environments.

First of all, the oxidation resistance of titanium alloy seamless pipes is very good. Titanium alloy has a low oxidation rate and can significantly slow down the oxidation reaction in high temperature environments. The oxide film generated on the surface of titanium alloy can prevent further penetration of oxygen molecules and effectively protect its internal structure from the effects of oxidation. Therefore, titanium alloy seamless pipes can maintain their original performance and stability in high temperature environments.

Titanium alloy seamless pipes have excellent high temperature resistance. Titanium alloy has a higher melting point, about 1668 degrees Celsius, which is much higher than other common metal materials such as stainless steel and aluminum alloys. In high temperature environments, titanium alloy seamless pipes can maintain high strength and hardness and are not easy to soften or deform. Therefore, titanium alloy seamless pipes can withstand high pressure and high stress under high temperature conditions and have good durability. Grade 12 Titanium Tube / Titanium Alloy Seamless Rectangular Tube / titanium heat exchanger tubing

Titanium alloy seamless pipes have good corrosion resistance. Titanium alloys can form a stable oxide film at high temperatures to prevent contact between corrosive media and titanium alloys, thereby reducing the occurrence of corrosion. Titanium alloy seamless pipes can withstand corrosion from various strong acids, strong alkali and salt water, and are widely used in chemical industry, marine engineering, oil and natural gas and other fields.

Titanium alloy seamless pipes also have high thermal conductivity. Titanium alloy has a high thermal conductivity and can quickly conduct heat at high temperatures to evenly distribute the temperature of the pipe to avoid local overheating or overcooling. This is very important for some equipment and processes that require high temperature accuracy.

Introduction to the manufacturing process of titanium plates

Titanium plate manufacturing process:

1. Hot forging: a forging process performed above the metal recrystallization temperature.

2. Hot rolling: a rolling process carried out at a temperature higher than the recrystallization temperature.

3. Cold rolling: a rolling process in which the plastic deformation temperature is lower than the recovery temperature.

4. Annealing: A metal heat treatment process that slowly heats the metal to a specific temperature, maintains it for a sufficient time and then cools it at an appropriate speed (usually slow cooling, sometimes controlled cooling). 5. Pickling: Immerse the parts in an aqueous solution such as sulfuric acid to remove oxide and other films on the metal surface of the titanium plate. It is the pre-treatment or intermediate treatment for electroplating, enamel, rolling, and other processes. Grade 5 Ti-6Al-4V Titanium Plate / Grade 7 Ti-0.2Pd Titanium Plate / Gr9 Ti-3Al-2.5V Titanium Plate

How should pure titanium pipes be welded?

Titanium alloy pipe welding is usually on-site all-position welding, which is much more difficult than stainless steel pipe welding. The weld area of ​​titanium and its alloys above 400°C must be protected because its chemical properties are particularly active and can easily absorb harmful gases. , leading to material performance degradation and even cracks. Therefore, special attention should be paid to the following matters when welding:

When welding titanium and its alloy pipes, the selection of welding materials is basically based on the principle of equal strength. When a suitable welding material cannot be found, the method of cutting it from the base metal can be used; and the selection of argon gas will directly affect the welding seam. The hardness and toughness also have a significant impact on the occurrence of welding cracks, so it is required to use high-purity argon (99.99%) (especially pure titanium).

The titanium tube should be cut and broken using cold processing methods, and it should not be overheated and discolored. Use a grinding wheel or stainless steel wire wheel to polish the internal and external surfaces of the groove to a metallic luster within a range of not less than 20mm. Use a scraper to trim the burrs on the groove and then polish it smooth to avoid hanging cloth wires during cleaning. bending titanium pipe / Gr23 Ti-6Al-4V ELI Titanium Tube / Grade 7 Ti-0.2Pd Titanium Tube

The quality of cleaning directly affects the occurrence of welding cracks and pores. It is usually pickled (3% HF + 35% HNO3 + H2O) first, then rinsed with clean water, finally dried, and wiped with acetone or alcohol before welding. The cleaned welding joint must be welded immediately and not more than 4 hours, otherwise it needs to be cleaned again. Do not use rubber gloves when cleaning. Use white cotton gloves instead.

The protection of the welding area is very important when welding titanium alloy pipes. It is similar to the welding of stainless steel pipes, but the requirements for gas protection are more stringent. The filling of argon in the pipe must continue until the end of the welding, and it cannot stop until the temperature of the welding area drops below 350°C; The outer front argon protection uses a large-diameter nozzle and an extended hood. In order to improve the protection effect, the hood does not end when the welding is completed. The air supply must be stopped and the hood must be removed after the temperature drops below 200°C.
