Titanium alloy and Its development course

Titanium is developed in the 1950 s a kind of important structure of the metal, titanium alloy has high strength, good corrosion resistance and high heat resistance and is widely used in various fields.Many countries in the world is to know the importance of the titanium alloy material, carries on the research and development, and the practical application.50 ~ 60 s of the 20th century, mainly is the development of aviation engine with high temperature and the body with the structure of the titanium alloy, titanium alloy developed a batch of corrosion resistant titanium alloy in the 70 s, 80 s, to further corrosion resistant titanium alloy and high strength titanium alloy.Titanium alloy is mainly used to produce aircraft engine compressor components, followed by the rockets and missiles and high-speed plane structure.TitaniumCN

Titanium is developed in the 1950 s a kind of important structure of the metal, titanium alloy has high strength, good corrosion resistance and high heat resistance and is widely used in various fields.Many countries in the world is to know the importance of the titanium alloy material, carries on the research and development, and the practical application.
First practical titanium alloy is in 1954 the successful development of Ti 6 al 4 v alloy, because of its heat resistance, strength, plasticity, ductility, formability, weldability and corrosion resistance and biocompatibility are better, and become the industry in ace alloy, titanium alloy, the alloy usage has 75% ~ 85% of all titanium alloys.Many other titanium alloy can be regarded as Ti 6 al 4 v alloy modification.
50 ~ 60 s of the 20th century, mainly is the development of aviation engine with high temperature and the body with the structure of the titanium alloy, titanium alloy developed a batch of corrosion resistant titanium alloy in the 70 s, 80 s, to further corrosion resistant titanium alloy and high strength titanium alloy.Using the temperature of the heat resistance of titanium alloy has been in the 50 s to 400 ℃ up to 600 ~ 650 ℃ in the 90 s.A2 (Ti3Al) and r (TiAl alloy, the titanium in the use of the engine parts by the engine is cold end (fan and the compressor) to the hot end of engine (turbine) direction.Titanium alloy for high strength, high plastic structure, with high strength and high tenacity, high modulus and high damage tolerance direction.
In addition, since the 1970 s, the Ti, Ni, Ti - Ni - Fe - Ni - Nb, Ti shape memory alloy, and increasingly wide application in engineering.Has developed hundreds of titanium alloy in the world, the most famous of the alloy has 20 ~ 30 kinds, such as Ti 6 al 4 v, Ti - 5-2.5 Sn, Ti - 2 al - 2.5 - Zr, Ti - 32 Mo, Ti, Mo, Ni, Ti - Pd, SP - 700, Ti, Ti - 6242-10-5-3, Ti - 1023, BT9, BT20, IMI829, IMI834
According to relevant statistics, in 2012 China's chemical industry with titanium volume of 25000 tons, less than in 2011.This is since 2009, our country chemical industry with titanium market negative growth for the first time.In recent years, the chemical industry has always been the largest use of titanium processing material, its dosage in titanium has remained at more than 50% of the total amount accounted, the proportion is as high as 55% in 2011.But as the economic downturn, the chemical industry not only decreased significantly in new projects, at the same time will also face adjustment of industrial structure, the partial products new capacity controlled, backward production capacity will be phased out.Affected, its shrinking of titanium processing material consumption has become a natural.Before this, there is industry insiders predict chemical industry with titanium content peaked in 2013 ~ 2015 years.At the current market point of view, the weakness in the overall economy in 2012 is likely to make chemical recession ahead of titanium.
