The use of titanium began in the early 1950s and has lasted for about half a century. The use of titanium began in aviation. High specific strength and good heat resistance make titanium become an important aviation structure material, and titanium was first used in aeroengine. The first titanium alloy used was the ti-6al-4v(TC4) alloy. This titanium alloy is the most widely used titanium alloy in the world. In the aviation application, the application of titanium also starts from the military aircraft. The most advanced aircraft in the modern era, such as fighter f-15, f-22, f-117, bomber B1, BlB, helicopter and large military transport aircraft, all use more titanium. Titanium has been used in commercial transport since the mid-1960s.
In the past 50 years, titanium is mainly used in four fields: aviation (aircraft and civil aircraft) and nuclear submarine, typical products are aero-engine compressor disc and blade, wing, ship shell; Chemical industry, metallurgy, electric power and other civil industrial sectors, the typical products are large chemical pressure vessels, various types of heat exchangers (plate, column, coil type) and pipelines, pumps, valves; Medical, sports and daily necessities, typical products are titanium bone, medical equipment, golf head, crafts, cooking utensils and glasses; (4) construction, automobile and other leading industries and the information industry. Titanium is now in vogue in iconic high-end buildings such as stadiums, museums and urban sculptures. Titanium has become a mature technology for valves and springs in high - grade automobile engines.
In the 2l century, with the maturity of titanium production technology, the decrease of cost and the deepening understanding of titanium from all walks of life. Titanium and titanium alloys will be more and more widely used.
Among the many applications of titanium, aviation applications still dominate. At present, 70% to 80% of the world's titanium brands and about 50% of the titanium materials are used in the field of aviation. Non-aviation applications are dominated by industrial pure titanium. Special titanium alloys, such as corrosion resistant titanium alloys.
Biomedical titanium alloy and other varieties are less. However, due to the limited number of aircraft, aviation applications are also limited. The overall trend for titanium applications is increasing in the proportion of non-aerospace applications. To promote the non-aviation application of titanium should be titanium industry and mechanical engineering.
