titanium wires Historical development of titanium alloys

Titanium is an important structural metal in the 1950s developed , titanium because of its high strength, corrosion resistance, and high heat resistance, is widely used in various fields . Many countries recognize the importance of titanium alloy materials , have their research and development , and has been applied .Titanium is the first practical United States in titanium wire 1954 successfully developed Ti-6Al-4V alloy , because of its heat resistance, strength , ductility, toughness , formability , weldability , corrosion resistance and biocompatibility are preferably , the titanium industry become ace alloy , the alloy of the amount of 75% to 85% account for all of the titanium alloy . Many other titanium alloys can be regarded as modified Ti-6Al-4V alloy.1950s and 1960s, mainly the development of high temperature titanium and titanium alloy airframe structures used in aircraft engine , the 1970s developed a number of corrosion resistant alloys, since the 1980s , corrosion resistance and high strength titanium alloy titanium further development. Temperature resistant titanium alloy 400 ℃ from the 1950s up to the 1990s 600 ~ 650 ℃. Appears A2 (Ti3Al) and r (TiAl) based alloys , titanium propulsion engines use part of the engine being cold side ( fan and compressor ) to the hot end of the engine ( turbine ) direction . The development of the high-strength titanium alloy structure , high plastic , high strength and high toughness , high modulus and high damage tolerance direction .In addition , since the 1970s , there was even a Ti-Ni, Ti-Ni-Fe, Ti-Ni-Nb shape memory alloys , etc. , and get increasingly widely used in engineering .World has been developed hundreds of titanium , most notably 20 to 30 kinds of alloys , such as Ti-6Al-4V, Ti-5Al-2.5Sn, Ti-2Al-2.5Zr, Ti-32Mo, Ti- Mo-Ni, Ti-Pd, SP-700, Ti-6242, Ti-10-5-3, Ti-1023, BT9, BT20, IMI829, IMI834 , etc. [ 2,4 ] .According to relevant statistics , in 2012 China's chemical industry with a capacity of 25,000 tons of titanium , a decrease over 2011 . This is since 2009 , China's chemical market with titanium first negative growth . In recent years , the chemical industry has been the largest user of titanium processing material , the amount of titanium proportion of the total amount has remained above 50% , in 2011 accounting for up to 55%. But with the economic downturn period , the chemical industry is not only new projects significantly reduced, while also facing the industrial structure adjustment, the new production of
some products can be controlled , backward production capacity will be phased out of the situation. Affected by its shrinking titanium wire price amount of titanium mill has become a matter of course . Prior to this , there will be insiders predict the chemical industry reached a peak of titanium in 2013 and 2015 . It seems that the current market performance , the overall weakness in the economy in 2012 may make the chemical industry recession titanium advance.
