Titanium alloys are classified according to their composition

Alpha alloy, (α + β) alloy and β alloy, China are represented by TA, TC, TB, respectively.
1 Alpha alloy contains a certain amount of elements of stable α phase, which is mainly composed of α phase in equilibrium. The α alloy has a small specific gravity, good heat resistance, good weldability and excellent corrosion resistance, and has the disadvantage of low room temperature strength, and is generally used as a heat resistant material and a corrosion resistant material. Alpha alloys are generally classified into full alpha alloys (TA7), near alpha alloys (Ti-8Al-1Mo-1V), and alpha alloys (Ti-2.5Cu) with small amounts of compounds. The 2 (α + β) alloy contains a certain amount of elements which stabilize the α phase and the β phase, and the structure of the alloy in the equilibrium state is the α phase and the β phase. The (α+β) alloy has medium strength and heat treatment strengthening, but the welding performance is poor. (α + β) alloys are widely used, and the production of Ti-6Al-4V alloy accounts for more than half of all titanium materials.
3 The β alloy contains a large amount of elements which stabilize the β phase, and the high temperature β phase can be retained to room temperature. The beta alloy is generally classified into heat treatable beta alloys (stabilized beta alloys and near metastable beta alloys) and thermally stable beta alloys. Heat treatable The β alloy has excellent plasticity in the quenched state and can achieve a tensile strength of 130 to 140 kgf/mm2 by aging treatment. Beta alloys are commonly used as high strength and high toughness materials. The disadvantages are that the ratio is high, the cost is high, the welding performance is poor, and the cutting process is difficult.
Titanium can be subjected to various pressure processing such as forging, rolling, extrusion, stamping, etc. In principle, the equipment used for heating steel can be used for heating titanium, and the atmosphere in the furnace is required to maintain a neutral or weak oxidizing atmosphere. Heated with hydrogen.
Titanium has a higher yield ratio (σ0.2/σb), generally between 0.70 and 0.95, and the deformation resistance is large, while the elastic modulus of titanium is relatively low. Therefore, titanium is difficult to process. Pure titanium has good welding properties, and the weld strength, ductility and corrosion resistance are similar to those of the base metal. In order to prevent contamination during welding, tungsten argon shielded welding is required.
The cutting process of titanium is difficult. The main reason is that the friction coefficient of titanium is large, the thermal conductivity is poor, and the heat is mainly concentrated on the tip of the blade, so that the tip is softened quickly. At the same time, the chemical activity of titanium is high, and the temperature rises to easily adhere to the tool, resulting in bond wear. When cutting, the tool material should be properly selected to keep the tool sharp and use a good cooling process.

Titanium production process

At present, the industrial method for the production of titanium metal is the Raul method, and the product is titanium sponge. The traditional process for making titanium is to melt the sponge titanium into an ingot and then process it into a titanium material. According to this, the main steps from the mining to the process of making titanium are: titanium ore -> mining -> mineral processing -> too concentrate -> enrichment -> titanium-rich material -> chlorination -> coarse TiCl4-> Refined->Pure TiCl4->Magnesium Reduction->Sponge Titanium->Fused Casting->Titanium Ingot->Processing->Titanium or Titanium Parts If the mining process is rutile in the above steps, it is not necessary to carry out enrichment and can directly carry out chlorine. The crude TiCI4 was obtained. In addition, the casting operation should be a metallurgical process, but sometimes it is also classified into the processing technology. The processing in the above process refers to plastic processing and casting. Plastic processing methods include forging, extrusion, rolling, stretching, and the like. It can process titanium ingots into various sizes of cakes, rings, plates, pipes, rods, profiles and other products, and can also be used to make parts and parts of various shapes by casting method. The plastic working of titanium and titanium alloy has large deformation resistance; the plasticity at room temperature, the yield limit and the strength limit ratio are high, the rebound is large, the gap is sensitive, the deformation process is easy to bond with the mold, and the harmful gas is easy to suck when heated. Plastic processing is more difficult than steel and copper. Therefore, the processing of titanium and titanium alloys must take into account these characteristics. Titanium is plastically processed, the size of the soil is not limited, and it can be mass-produced, but the yield is low, and a large amount of waste residue is generated during the processing. In view of the above shortcomings of titanium plastic working, a powder metallurgy process of titanium has been developed in recent years. The powder metallurgy process of titanium is the same as ordinary powder metallurgy, except that the sintering must be carried out under vacuum. It is suitable for the production of large-volume, small-sized parts, especially for the production of complex parts. This method requires almost no processing, and has a high yield. It can fully utilize titanium scrap as a raw material and reduce production costs, but cannot produce large-sized titanium parts. The powder metallurgy process of titanium is: titanium powder (or titanium alloy powder) -> sieve -> mixing -> press forming -> sintering -> auxiliary processing -> titanium products. Principle Process for Titanium Production In addition to pure titanium, titanium has produced nearly 30 grades of titanium alloys in the world. The most widely used titanium alloys are Ti-6Al-4V, Ti-5Al-2.5Sn, etc.

Characteristics of titanium rods

Titanium alloys are mainly used to make aircraft engine compressor components, followed by structural components for rockets, missiles and high-speed aircraft. In the mid-1960s, titanium and its alloys were used in the general industry for the production of electrodes for the electrolysis industry, condensers for power stations, heaters for petroleum refining and seawater desalination, and environmental pollution control devices. Titanium and its alloys have become a corrosion resistant structural material. It is also used to produce hydrogen storage materials and shape memory alloys.
