Titanium alloys in aerospace
In aviation, titanium alloys are mainly used to make jet engine compressor disks, blades, nozzles, landing gear, fuselage skins, and fasteners. For example, the U.S. Airbus A380, Boeing 787 and F-22, F-35 fighters all use titanium alloys in a large amount. Among them, the amount of titanium in F-22 fighters is as high as 41%; in space, titanium alloys have high specific strength. And with excellent plasticity and toughness, it is widely used in the fields of rockets, missiles, and spacecraft, such as high-pressure vessels, fuel storage tanks, spacecraft cabins, structural skeletons and other components; in the field of shipbuilding industry, titanium alloys are widely used Used as pressure boat body, structure body, buoyancy system sphere, pump body and plywood fittings, etc .; titanium alloy can be used as heat exchanger, reaction tower, autoclave, etc. in the chemical and petroleum industry fields; titanium alloy is non-toxic and corrosion-resistant And, it has a good affinity with body tissues, and has been widely used in the manufacture of medical devices and surgical implants; titanium alloys are mainly used in automobile driving devices and automobile chassis in automobiles. The use of titanium alloys for engine valves and connecting rods, valve springs, and valve spring seats not only improves fuel efficiency, reduces noise and vibration, increases service life, but also increases torque and allows components to have less deflection.
