Titanium is an important structural metal in the 1950s developed, titanium because of its high strength, corrosion resistance, and high heat resistance and are widely used in various fields. Many countries recognize the importance of titanium alloy materials, have their research and development of titanium stainless steel reactor, and has been applied. Titanium is the first practical American in 1954 successfully developed Ti-6Al-4V alloy, because of its heat resistance, strength, ductility, toughness, formability, weldability, corrosion resistance and biocompatibility are titanium filter better, and become the ace of titanium alloy industry, which accounts for the use of the alloy of 75% to 85% of all titanium alloys. Many others can be seen as a modification of titanium alloy Ti-6Al-4V alloy. . 1950s and 1960s, titanium, titanium alloy is mainly structural development thermowell aircraft engine and airframe high temperature titanium alloy used in the 1970s to develop a number of corrosion resistant alloys, since the 1980s, corrosion resistant titanium and further development of high-strength titanium alloy. Temperature resistant titanium alloys 400 ℃ from the 1950s up to the 1990s 600 ~ 650 ℃. Appear A2 (Ti3Al) and r (TiAl) based alloys, titanium engine parts being propelled by the use of the cold side of the engine (fan and compressor) to the hot end of the engine (turbo) direction. Titanium alloy development to high-strength, high plastic, high strength and high toughness, high modulus and high damage tolerance direction. _ Titanium titanium thermowell (certified) _ titanium by Special Metals Co., Ltd.
