Wholesale high strength TC4 titanium alloy plate and high temperature resistant TA2 titanium plate

 
Titanium alloy is an alloy composed of titanium and other elements
There are two kinds of homogeneous and heterogeneous crystals of titanium: titanium is an isomer with a melting point of 1668 ℃
When it is lower than 882 ℃, it has a close packed hexagonal lattice structure, which is called & alpha- Titanium; Above 882 ℃, it has a body centered cubic structure, which is called & beta- Titanium
Using the different characteristics of the above two structures of titanium, appropriate alloy elements are added to gradually change its phase transformation temperature and component content to obtain titanium alloys with different structures

Alloy elements can be divided into three categories according to their influence on phase transformation temperature: stable alpha; The elements that increase the phase transition temperature are & alpha; Stable elements include aluminum, carbon, oxygen and nitrogen
Aluminum is the main alloying element of titanium alloy
It has obvious effect on improving the strength at room temperature and high temperature, reducing the specific gravity and increasing the elastic modulus of the alloy
Stable & beta; The elements that reduce the phase transition temperature are & beta; Stable elements can be divided into isomorphic and eutectoid types
The former includes molybdenum, niobium, vanadium, etc; The latter includes chromium, manganese, copper, iron, silicon, etc
The elements that have little effect on the phase transition temperature are neutral elements, such as zirconium, tin and so on

Oxygen, nitrogen, carbon and hydrogen are the main impurities in titanium alloys
Oxygen and nitrogen in & alpha; It has a large solubility in the phase, which has a significant strengthening effect on titanium alloy, but reduces the plasticity
It is generally stipulated that the contents of oxygen and nitrogen in titanium are less than 0
15-0
2% and 0
04-0
05% respectively
Hydrogen in & alpha; The solubility in the phase is very small
Too much hydrogen dissolved in titanium alloy will produce hydride and make the alloy brittle
Generally, the hydrogen content in titanium alloy is controlled below 0
015%
The dissolution of hydrogen in titanium is reversible and can be removed by vacuum annealing
At room temperature, titanium alloys have three kinds of matrix structures, and titanium alloys can be divided into the following three categories: & alpha; Alloy, (& alpha; + & beta;) Alloy and & beta; Alloy
