What Are The Characteristics Of Titanium Alloy?

Titanium alloy

Titanium alloy is a new structural material, it has excellent comprehensive properties, such as low density (~4.5g·cm-3), high specific strength and fracture toughness, good fatigue strength and crack growth resistance, good low temperature toughness, excellent corrosion resistance, some titanium alloy maximum working temperature is 550ºC, expected to reach 700ºC. Therefore, it is increasingly widely used in aviation, aerospace, chemical industry, shipbuilding and other industrial sectors, and develops rapidly. The ratio of σ0.2/ density to temperature of light alloys, steels, etc. Titanium alloys is higher than that of other light metals, steels, and nickel alloys, and this advantage can be maintained up to about 500ºC, so some titanium alloys are suitable for manufacturing gas turbine components. About 80% of titanium production is used in the aerospace and aerospace industries. For example, in the body structure of the B-1 bomber of the United States, titanium alloy accounts for about 21 percent, which is mainly used to make the fuselage, wings, skin and bearing components. The body structure of the F-15 fighter jet uses up to 7,000 kg of titanium alloy, accounting for about 34% of the structure weight. About 5% of the structural parts of Boeing 757 are made of titanium alloy, with a dosage of 3,640 kg. The DC10 made by McDonnell Douglas (Mc-donnell-dounlas) uses 5,500kg of titanium alloy, more than 10% of the structure's weight. Titanium USE in chemical and general engineering: THE United States accounts for about 15 percent of its production and Europe for about 40 percent. Due to the excellent corrosion resistance, good mechanical properties and qualified histocompatibility, titanium and its alloy can be used to make biomaterials such as prosthetic devices.
