Analysis of titanium forging manufacturing process technology!

1. Main forging methods of titanium forgings

1. Free forging

Applicable to forgings with simple shapes and low precision requirements, relying on manual operation, and low material utilization rate.

The process is flexible, but the deformation and hammering frequency need to be strictly controlled.

2. Die forging process

Open die forging: using a die with flash groove, controlling the metal flow in stages, and removing the flash during final forging, suitable for batch production of complex shape forgings.

Closed die forging: flash-free design, high material utilization rate, better precision, but strict requirements on die strength and temperature control.

3. Extrusion and rolling

The extrusion process is extruded through the die hole, suitable for long strip/tube forgings, with high material density, but large equipment investment.

Rolling controls the shape through continuous deformation, with high efficiency and can accurately adjust the size of the plate/profile. Gr2 Pure Titanium Foil / forge titanium ring / ASTM B265 Cold Rolling Titanium Plate

2. Core process flow

1. Open forging

The initial temperature is selected to be 150-250℃ above the β phase transformation point, and the "light-heavy-stable" three-stage hammering strategy is adopted. Intermediate annealing is required when the cumulative deformation is greater than 70%.

Multi-directional forging cycle improves the uniformity of the organization, and the deformation of each fire is controlled at 50%-80%.

2. Special process optimization

U-shaped titanium alloy forgings adopt a "one"-shaped step billet design, which is formed by special tire molds and punches in steps. The cross-section of the bar is 1.1-1.25 times that of the rough shape to improve the accuracy.

Right-angle trapezoidal forgings optimize the deformation distribution through multi-fire forging, and the single deformation is 20%-50%.

3. Key points of quality control

1. Temperature and lubrication

The temperature fluctuation is monitored by infrared thermal imaging throughout the process, and the final forging temperature must be higher than the critical value of β brittleness to avoid cracks.

Graphite-based lubricants are used to reduce mold friction, and the R angle of the corners is greater than 15mm to prevent stress concentration.

2. Organization and defect prevention and control

β brittleness is repaired by controlling the heating temperature and plastic deformation.

The residual casting structure needs to ensure that the forging ratio is greater than 3:1, and the deformation rate in the final forging stage is dynamically adjusted.

IV. Heat treatment process

1. Quenching and tempering

α+β type titanium forgings need to be quenched after preheating at 600-650℃, and the tempering temperature is 400-500℃.

2. Solution and aging

α+β type solution treatment temperature is 980℃, and β type is treated at 775-900℃; aging temperature is 480-600℃, and it lasts for 2-16 hours to precipitate strengthening phase.

Introduction to the performance of titanium plates and their application range

Titanium is a very active metal. Its chemical symbol is ti and its atomic number is 22. It is rich in resources and ranks third in the earth's reserves. It can be said that it is inexhaustible. It is a silver metal with a specific gravity of about 4.51 and a melting point of 1668℃. It is corrosion-resistant, has a long service life, and has a high scrap recycling price. The value of titanium scrap after scrapping is still equivalent to more than 60% of the purchase value of raw materials. It can be said that titanium material is the least wasteful material. Titanium is green and environmentally friendly and will not cause any adverse effects on the environment. The high cost of materials such as titanium plates is only the first large investment, but if it is calculated carefully after many years of use, titanium plates are an economical and practical ideal material. The ores used to produce titanium in industry include rutile, ilmenite and titanomagnetite. Due to the difficulty of separation and extraction, the metal titanium with industrial significance was not produced until the 1940s. Therefore, titanium is generally called a rare light metal.

As different products in different fields require different titanium and titanium alloy products, people process them into titanium plates, titanium rods, titanium tubes, titanium strips, titanium wires, etc., which can be provided to the majority of demanders in deep-processed shapes to meet the needs of different fields. Among them, titanium plates, titanium rods, and titanium tubes are the most widely used. titanium coil strip / Titanium Hex Nut / Grade 23 Ti-6Al-4V ELI Titanium Plate

Titanium and titanium alloys have low density and high tensile strength. In the range of -253-600 degrees Celsius, its specific strength is almost the highest among metal materials. It can form a thin and hard oxide film in a suitable oxidizing environment, which has excellent corrosion resistance. In addition, it also has the characteristics of non-magneticity and small linear expansion coefficient. This makes titanium and alloys first called important aerospace structural materials, and then promoted to shipbuilding, chemical industry and other fields, and has developed rapidly. Especially in the chemical industry, more and more products use titanium and titanium alloy products, such as petrochemicals, fibers, pulp, fertilizers, electrochemistry and seawater desalination industries, as exchangers, reaction towers, synthesizers, autoclaves, etc. Among them, titanium plates are used as titanium electrolytic plates and titanium electrolytic cells in electrolysis and sewage desalination, and are used as tower bodies and kettle bodies in titanium reaction towers and titanium reactors.

Titanium plate has good corrosion resistance

Titanium plate stands out among many metal materials for its good corrosion resistance. This material can maintain good performance in a variety of harsh environments and show strong corrosion resistance. Its corrosion resistance is mainly due to the dense oxide film formed on its surface. When it is exposed to the air, a thin and dense titanium dioxide (TiO₂) oxide film will quickly form on the surface. This oxide film can effectively prevent the contact between the corrosive medium and the titanium matrix, thereby playing a protective role.

In the marine environment, the corrosion resistance of titanium plates is particularly outstanding. Seawater contains a large amount of chloride ions, which are highly corrosive to ordinary metals, but it can be used in seawater for a long time without being corroded. For example, in shipbuilding, hull parts and seawater pipelines made of titanium plates can effectively resist the erosion of seawater, greatly extending the service life of ships. In the chemical industry, titanium plates also perform well. It can withstand corrosion from a variety of acid and alkali solutions, such as sulfuric acid, hydrochloric acid, sodium hydroxide, etc. In some chemical equipment, reactors, heat exchangers and other components made of titanium plates can operate stably in highly corrosive media, reducing the maintenance and replacement costs of equipment. Grade 23 Titanium Plate / thin titanium plate
