Use of TC4 titanium alloy, titanium alloy rod and titanium alloy sheet
TC4 titanium alloy, titanium alloy rod and titanium alloy sheet have high strength and low density, good mechanical properties, good toughness and corrosion resistance. In addition, the titanium alloy has poor processability and is difficult to cut, and it is very easy to absorb impurities such as hydrogen, nitrogen, nitrogen and carbon during hot working. There is also poor wear resistance and complicated production processes.
The industrial production of titanium began in 1948. The development of the aviation industry has enabled the titanium industry to grow at an average annual growth rate of about 8%. At present, the annual output of titanium alloy processing materials in the world has hit more than 40,000 tons, and nearly 30 titanium alloy grades. The more widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2, and TA3).
TC4 titanium alloy is mainly used to make aircraft engine compressor parts, followed by structural parts of rockets, missiles and high-speed aircraft. In the mid-1960s, titanium and its alloys were used in the general industry for the production of electrodes for the electrolysis industry, condensers for 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. It is also used to produce hydrogen storage materials and shape memory alloys. Titanium alloy is a new important structural material used in the aerospace industry. Its specific gravity, strength and service temperature are between aluminum and steel, but its specific strength is high and it has excellent seawater corrosion resistance and ultra-low temperature performance.
Titanium alloys generally account for 20%-30% of the total structure of aeroengines. They are mainly used in the manufacture of compressor parts, such as forged titanium fans, compressor discs and blades, cast titanium compressors, and intermediate machines. Bearing housing, etc. The spacecraft mainly uses titanium alloy's high specific strength, corrosion resistance and low temperature resistance to manufacture various pressure vessels, fuel tanks, fasteners, instrument straps, frames and rocket housings. Artificial earth satellites, lunar modules, manned spacecraft and space shuttles also use titanium alloy welded parts.
