Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance. In addition, titanium alloys have poor process performance and are difficult to process. During thermal processing, they easily absorb impurities such as hydrogen, oxygen, nitrogen, and carbon. It also has poor wear resistance and complex production process. Industrial production of titanium began in 1948. The needs of the development of the aviation industry have caused the titanium industry to develop at an average annual growth rate of about 8%. The world's annual output of titanium alloy processing materials has reached more than 40,000 tons, with nearly 30 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).

Titanium alloys are mainly used to make aircraft engine compressor parts, followed by structural parts for rockets, missiles and high-speed aircraft. In the mid-1960s, titanium and its alloys have been used in general industry to make electrodes in the electrolysis industry, condensers in 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. In addition, it is also used to produce hydrogen storage materials and shape memory alloys.

China began research on titanium and titanium alloys in 1956; in the mid-1960s, it began industrial production of titanium materials and developed TB2 alloys.

Titanium alloy is a new important structural material used in the aerospace industry. Its specific gravity, strength and operating temperature are between those of aluminum and steel, but it is stronger than aluminum and steel and has excellent resistance to seawater corrosion and ultra-low temperature performance. In 1950, the United States first used it on the F-84 fighter-bomber as non-load-bearing components such as rear fuselage heat shields, wind deflectors, and tail cowls. Since the 1960s, the use of titanium alloys has moved from the rear fuselage to the middle fuselage, partially replacing structural steel in the manufacture of important load-bearing components such as bulkheads, beams, and flap slide rails. The use of titanium alloys in military aircraft has increased rapidly, reaching 20% to 25% of the weight of the aircraft structure. Since the 1970s, civil aircraft have begun to use titanium alloys in large quantities. For example, the Boeing 747 passenger aircraft uses more than 3,640 kilograms of titanium. Titanium is used in aircraft with Mach numbers greater than 2.5 mainly to replace steel to reduce structural weight. Another example is the American SR-71 high-altitude and high-speed reconnaissance aircraft (flying Mach number 3, flying altitude 26,212 meters), titanium accounts for 93% of the aircraft's structural weight, and is known as an "all-titanium" aircraft. When the thrust-to-weight ratio of the aeroengine increases from 4 to 6 to 8 to 10, and the compressor outlet temperature increases from 200 to 300°C to 500 to 600°C, the low-pressure compressor disc and blades originally made of aluminum must be Switch to titanium alloy, or use titanium alloy instead of stainless steel to make high-pressure compressor disks and blades to reduce structural weight. In the 1970s, the amount of titanium alloy used in aeroengines generally accounted for 20% to 30% of the total weight of the structure. It was mainly used to manufacture compressor parts, such as forged titanium fans, compressor discs and blades, cast titanium compressor casings, and intermediaries. casing, bearing housing, etc. Spacecraft mainly utilize the high specific strength, corrosion resistance and low temperature resistance of titanium alloys to manufacture various pressure vessels, fuel tanks, fasteners, instrument straps, structures and rocket casings. Artificial earth satellites, lunar modules, manned spacecraft and space shuttles also use titanium alloy plate welding parts.
