TI-811 Good formability titanium Alloy Steel Bar
Titanium alloy tubes are tubes made of titanium alloys. Titanium alloys can be divided into three categories according to organization. (1 Titanium is added with aluminum and tin elements. 2 Titanium is added with aluminum chromium molybdenum vanadium and other alloy elements. 3 Titanium is added with aluminum and vanadium and other elements.) They have high mechanical properties, excellent stamping performance, and can be used for various In various forms of welding, the strength of the welded joint can reach 90% of the strength of the base metal, and the cutting performance is good. Titanium tube has high corrosion resistance to chloride, sulfide and ammonia. Titanium has higher corrosion resistance in seawater than aluminum alloys, stainless steels, and nickel-based alloys. Titanium is also resistant to water impact.
The elastic modulus of titanium alloy (annealed state) is 1.078 × 10-1.176 × 10MPa, which is about half of steel and stainless steel.
4. Excellent high and low temperature performance. At high temperatures, titanium alloys can still maintain good mechanical properties, their heat resistance is much higher than aluminum alloys, and the working temperature range is wider. The working temperature of new heat-resistant titanium alloys can reach 550-600 ºC; However, the strength of the titanium alloy instead increases at room temperature, and has good toughness. The low-temperature titanium alloy can maintain good toughness at -253 ° C.
2)Application
Titanium alloy is mainly used to make aircraft engine compressor components, followed by rocket, missile and high-speed aircraft structural parts. In the mid-1960s, titanium and its alloys have been used in general industry, for making electrodes in the electrolysis industry, condensers in power plants, 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.
The alpha alloy contains a certain amount of elements that stabilize the alpha phase, and is mainly composed of the alpha phase in equilibrium. Alpha alloy has a small specific gravity, good thermal strength, good weldability and excellent corrosion resistance. The disadvantage is that the room temperature strength is low, and it is usually used as a heat-resistant material and corrosion-resistant material. Alpha alloys are usually divided into full alpha alloys (TA7), near alpha alloys (Ti-8Al-1Mo-1V) and alpha alloys (Ti-2.5Cu) with a small amount of compounds.
1Titanium alloys can be divided into three categories according to the phase composition: α alloys, (α + β) alloys and β alloys. China is represented by TA, TC and TB respectively.

The (α + β) alloy contains a certain amount of elements that stabilize the α and β phases, and the structure of the alloy in the equilibrium state is the α and β phases. (α + β) alloy has medium strength and can be strengthened by heat treatment, but the welding performance is poor. (α + β) alloys are widely used, and the output of Ti-6Al-4V alloy accounts for more than half of all titanium materials.

β alloy contains a large amount of elements that stabilize β phase, which can keep all high temperature β phase to room temperature. Beta alloys can generally be divided into heat treatable beta alloys (meta-stable beta alloys and near meta-stable beta alloys) and thermally stable beta alloys. Heat treatable β alloy has excellent plasticity in the quenched state, and can achieve tensile strength of 130 ~ 140kgf / mm2 through aging treatment. Beta alloys are generally used as high-strength and high-toughness materials. The disadvantages are large specific gravity, high cost, poor welding performance, and difficult machining.
2Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high specific strength, good corrosion resistance, and high heat resistance. Many countries in the world have realized the importance of titanium alloy materials, and have successively researched and developed them, and have obtained practical applications. Titanium is a type IVB element in the periodic table. It looks like steel and has a melting point of 1 672 ºC. It is a refractory metal. Titanium is abundant in the earth's crust, much higher than common metals such as Cu, Zn, Sn, and Pb. China's titanium resources are extremely rich. Only in the large-scale vanadium-titanium magnetite found in Panzhihua, Sichuan, the associated titanium metal reserves are approximately 420 million tons, which is close to the sum of the proven titanium reserves abroad. Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium-molybdenum, titanium-palladium alloys, etc.), low-temperature alloys, and special functional alloys (titanium-iron hydrogen storage materials and titanium-nickel memory alloys), etc. .
3)Titanium alloy classification
Fold by organization
(1 Titanium adds aluminum and tin elements. 2 Titanium adds aluminum chromium molybdenum vanadium and other alloy elements. 3 Titanium adds aluminum and vanadium and other elements.) Titanium alloy has high strength and small density, good mechanical properties, toughness and The corrosion resistance is very good. In addition: the titanium alloy has poor process performance and difficult cutting. In hot processing, it is very easy to absorb impurities such as oxyhydrogen, nitrogen, carbon, etc. There is also poor wear resistance, and the production process is complicated.
Fold by mixed elements
An alloy composed of titanium and other elements. The industrial production of titanium began in 1948. The need for the development of the aviation industry has enabled the titanium industry to grow at an average annual growth rate of about 8%. At present, the annual output of titanium alloy processed materials in the world has reached more than 40,000 tons, and there are nearly 30 kinds of titanium alloy grades. The most widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).
Fold by use
Titanium alloys can be divided into heat-resistant alloys, high-strength alloys, corrosion-resistant alloys (titanium-molybdenum, titanium-palladium alloys, etc.), low-temperature alloys, and special functional alloys (titanium-iron hydrogen storage materials and titanium-nickel memory alloys), etc. . The composition and properties of typical alloys are shown in the table.

6)Advantages of titanium alloy
Compared with other metal materials, titanium alloys have the following advantages:
A)The specific strength (tensile strength / density) is higher (see figure), the tensile strength can reach 100 ~ 140kgf / mm2, and the density is only 60% of steel.
B)The medium temperature strength is good, the use temperature is a few hundred degrees higher than that of aluminum alloy, it can still maintain the required strength at medium temperature, and can work for a long time at a temperature of 450 ~ 500 ºC.
C)Good corrosion resistance, a uniform and dense oxide film is immediately formed on the titanium surface in the atmosphere, which has the ability to resist the erosion of various media. Generally, titanium has good corrosion resistance in oxidizing and neutral media, and is more excellent in seawater, wet chlorine and chloride solutions. But in a reducing medium, such as hydrochloric acid, the corrosion resistance of titanium is poor.
D) Titanium alloys with good low temperature performance and extremely low gap elements, such as TA7, can maintain a certain plasticity at -253 ºC.
E)Low elastic modulus, small thermal conductivity, and no ferromagnetism.
F) High hardness.
G)Poor stamping and good thermoplasticity.
Heat treatment Titanium alloy can obtain different phase composition and structure by adjusting the heat treatment process. It is generally believed that fine equiaxed structures have better plasticity, thermal stability and fatigue strength; needle-like structures have higher endurance strength, creep strength and fracture toughness; equiaxed and needle-like mixed structures have better comprehensive properties.
Commonly used heat treatment methods are annealing, solution treatment and aging treatment. Annealing is to eliminate internal stress, improve plasticity and organizational stability to obtain better overall performance. Generally, the annealing temperature of α alloy and (α + β) alloy is chosen to be 120 ~ 200 ºC below the transition point of (α + β)-→ β phase; solid solution and aging treatment are rapid cooling from high temperature area to obtain martensite α ′ Phase and meta-stable β phase, and then incubate in the middle temperature zone to decompose these meta-stable phases to obtain finely dispersed second phase particles such as α phase or compound to achieve the purpose of strengthening the alloy. Normally, the quenching of (α + β) alloy is carried out at 40 ~ 100 ºC below the transition point of (α + β)-→ β phase, and the quenching of metastable β alloy is 40 ~ 80 ºC above the transition point of (α + β)-→ β phase get on. Aging treatment temperature is generally 450 ~ 550 ºC. In addition, in order to meet the special requirements of the workpiece, the industry also adopts double annealing, isothermal annealing, β heat treatment, deformation heat treatment and other metal heat treatment processes.
