Titanium is an allotrope with a melting point of 1720 °C. When it is lower than 882 °C, it has a close-packed hexagonal lattice structure, which is called α titanium; when it is above 882 °C, it has a body-centered cubic lattice structure, which is called β titanium. Using the different characteristics of the above two structures of titanium, appropriate alloying elements are added to gradually change the phase transition temperature and phase content to obtain titanium alloys with different structures. At room temperature, titanium alloys have three matrix structures, and titanium alloys are divided into the following three categories: α alloys, (α+β) alloys and β alloys. China is represented by TA, TC, and TB, respectively.
Alpha titanium alloy
It is a single-phase alloy composed of α-phase solid solution. Whether it is at ordinary temperature or at higher practical application temperature, it is α-phase, with stable structure, higher wear resistance than pure titanium, and strong oxidation resistance. At the temperature of 500 ℃ ~ 600 ℃, it still maintains its strength and creep resistance, but it cannot be strengthened by heat treatment, and the room temperature strength is not high.
Beta titanium alloy
It is a single-phase alloy composed of β-phase solid solution. It has high strength without heat treatment. After quenching and aging, the alloy is further strengthened, and the room temperature strength can reach 1372~1666MPa; but the thermal stability is poor, and it is not suitable for use at high temperatures.

α+β titanium alloy
It is a dual-phase alloy with good comprehensive properties, good structural stability, good toughness, plasticity and high temperature deformation properties, and can be well processed by hot pressing, and can be quenched and aged to strengthen the alloy. The strength after heat treatment is about 50% ~ 100% higher than that in the annealed state; the high temperature strength is high, and it can work for a long time at a temperature of 400 ° C ~ 500 ° C, and its thermal stability is inferior to that of α titanium alloy.
Among the three titanium alloys, α titanium alloy and α+β titanium alloy are the most commonly used; α titanium alloy has the best machinability, followed by α+β titanium alloy, and β titanium alloy is the worst. The code name of α titanium alloy is TA, the code name of β titanium alloy is TB, and the code name of α+β titanium alloy is TC.
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.
Heat treatment Titanium alloys can obtain different phase compositions and structures by adjusting the heat treatment process. It is generally believed that the fine equiaxed structure has good plasticity, thermal stability and fatigue strength; the needle-like structure has high lasting strength, creep strength and fracture toughness; the equiaxed and acicular mixed structure has good comprehensive properties.
Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance.The titanium tube is light in weight, high in strength and superior in mechanical properties. It is widely used in heat exchange equipment, such as shell and tube heat exchangers, coil heat exchangers, serpentine heat exchangers, condensers, evaporators and conveying pipes, etc. Many nuclear power industries use titanium tubes as standard tubes for their units
