Titanium and it application



Titanium is a chemical element, chemical symbol Ti, atomic number 22, in the periodic table of the chemical 


element is located in the fourth cycle, the first IVB. Is a silver white transition metal, which is characterized


 by light weight, high strength, with a metallic luster, corrosion resistance to wet chlorine.


Titanium is considered to be a rare metal, which is dispersed and difficult to extract in nature. But it is 


relatively rich in all elements in the tenth place. Titanium ores are mainly of titanium iron ore and rutile, 


widely distributed in the earth's crust and lithosphere. Titanium also exists in almost all biological, rock, 


water and soil. Extraction of titanium from the main ore requires the use of Kroll or Hunter. Titanium is the 


most common compound of titanium dioxide, which can be used in the manufacture of white pigment. Other 


compounds including tetrachloride titanium (TiCl4) (as catalyst and for the manufacture of smoke or air 


text) and titanium trichloride (TiCl3) (for the production of polypropylene reactor).

Titanium tube performance


Titanium is a new type of metal, properties of titanium and contains carbon, nitrogen, hydrogen and oxygen 


impurity content related, the most pure titanium iodide impurity content is not more than 0.1%, but the


 strength low, high plasticity. 99.5% of industrial pure titanium properties: density p =4.5g/cm3 melting for 


1725 DEG C, coefficient of thermal conductivity lambda =15.24W/ (m-k), the tensile strength of the sigma 


b=539MPa, the elongation%, section shrinkage rate of PSI = 25%, elastic modulus E=1.078 * 105Mpa, 


hardness HB195.


(1) high strength


Titanium alloy density is about 4.5g/cm3, only 60% of steel, the strength of pure titanium was close to 


ordinary steel strength, high strength titanium alloy than many alloy structural steel strength. The titanium


 alloy strength (strength / density) is much larger than other metal structure materials, see table 7-1, the unit 


can produce high strength, good rigidity, light parts and titanium  components. The current aircraft engine


 components, skeleton, skin, titanium fasteners and landing gear and so the use of titanium alloy.


(2) high thermal strength


Using temperature than the aluminum alloy high several Baidu, the required strength remains at moderate

\

 temperatures, at 450 to 500 DEG C temperature long-term work these two kinds of titanium alloy in the 150

 

DEG C to 500 DEG C still has very high specific strength, and aluminum alloy at 150 DEG C than strength 


decreased significantly. The working temperature of titanium alloy is 500 DEG C, Aluminum Alloy at 200 


DEG C.


(3) good corrosion resistance


Titanium alloy in humid air and seawater, the corrosion resistance is much better than the stainless steel; 


pitting corrosion, acid corrosion, stress corrosion resistance is particularly strong in; of alkali, chloride, 


chlorine organic materials, nitric acid, sulfuric acid has excellent corrosion resistance. But with titanium on


 corrosion resistance of chromium and oxygen reduction medium difference.


(4) good low temperature performance


Titanium alloy at low temperature and ultra low temperature, can still maintain its mechanical properties. 


Good low temperature performance of titanium alloy, low interstitial elements such as TA7, under -253 DEG 


C can maintain a certain degree of plasticity. Therefore, the titanium alloy is a kind of important structural 


materials at low temperature.


(5) chemical activity



The chemical activity of titanium, have a strong chemical reaction with O in the atmosphere, N, H, CO,CO2,


 water vapor and ammonia etc.. 


When carbon content is larger than 0.2%, the formation of hard tic in titanium alloy; when the temperature


 is higher, and the role of n will form a surface layer of tin hard; in more than 600 DEG C, titanium oxygen 


absorption and high hardness of the hardened layer is formed; hydrogen content increased, brittle layer is 


formed. The absorption of gases produced by the depth of brittle surface is 0.1 ~ 0.15 mm, the degree of 


hardening is 20% ~ 30%. The chemical affinity of titanium is also large, easy to produce adhesion and 


friction surface.


(6) small thermal conductivity, low elastic modulus



A =15.24W/ thermal conductivity of titanium nickel (m.K) about 1/4, iron 1/5, aluminum 1/14, and thermal 


conductivity of titanium alloy than the thermal conductivity of titanium decreased about 50%. Elastic 


modulus of titanium alloy is about 1 / 2 of the steel, so the poor rigidity, easy deformation, not making 


elongated rod and thin walled parts, cutting springback amount of machined surface is large, about 2 ~ 3 


times the stainless steel, causing the tool rake face intense friction, adhesion, adhesive wear.


Use of titanium tube



Titanium alloy with high strength and density, good mechanical properties, good toughness and corrosion 


resistance. in addition.


2.Titanium round bars and titanium hex bars



The industrial production of titanium is the beginning of 1948. 


The needs of the aviation industry to carry


 out the titanium industry to grow at an average annual rate of about 8%. At present, the annual output of international titanium


 alloy processing material has reached 4 tons, nearly 30 kinds of titanium alloy trademark. The most widely used titanium alloys are


 Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and commercially pure titanium (TA1, TA2, and TA3). Titanium alloy is mainly used for the 


production of aircraft engine compressor parts, followed by the layout of the rocket, missile and high-speed aircraft. In the mid-


1960s, titanium and its alloy has usually used in industrial for making electrode electrolysis industry, power station condenser, oil


 essence and desalination of sea water heater and environmental pollution control equipment. Titanium and its alloys have 


become a corrosion resistant material.


Also used in the production of hydrogen storage materials and shape memory alloys, etc.. Titanium alloy is 


used in aerospace industry a new important layout data, density, strength and use temperature between 


aluminum and steel, but specific strength is high and it has excellent resistance to seawater corrosion 


function and ultra low temperature function. Amount of titanium alloys in aero engine typically accounts for


 20% of the total weight of the layout to 30%, first and foremost for the production of compressor 


components, such as casting titanium fan and compressor disk and blade, casting titanium compressor 


machine box, intermediary casing, bearing housing. Spacecraft first using titanium alloy of high specific 


strength, corrosion resistance and high temperature resistant performance to make all pressure vessels, fuel 


tank, fasteners, instrument strap, framework and rocket shell. Artificial earth satellite, lunar module, 


manned spaceship and space shuttle are also used in the welding of titanium alloy sheet.

Edit this paragraph introduces alloy folding


Based on the phase composition of titanium alloy can be divided into three categories: alpha (alpha + beta)


 alloy, alloy and alloy China beta, TA, TC and TB respectively to said.


The alpha alpha stable element alloy containing a certain amount of phase, the equilibrium state is mainly 


composed of alpha phase composition. A small proportion of alloy, heat resistance, good weldability and 


excellent corrosion resistance. The disadvantage is the strength at room temperature is low, usually used as 


heat resistant materials and corrosion resistant material. Alpha alloy usually can be divided into all alpha 


alloy (TA7), near alpha alloy (Ti-8Al-1Mo-1V) and a small amount of alpha alloy compounds (Ti-2.5Cu). II 


(alpha + beta) stable elements of alpha and beta alloys containing a certain amount of phase equilibrium,


 alloy microstructure for the alpha and beta phases. (alpha + beta) alloy with moderate intensity, and 


strengthened by heat treatment, but the welding performance. (alpha + beta) alloy is widely used, where Ti-


6Al-4V alloy production accounted for more than half of all titanium.



The beta alloys containing a large number of stable phase elements, the high temperature phase all the 


reservations to room temperature. Beta alloys usually can be divided into heat treatment (metastable beta 


beta alloy alloy and near metastable beta alloys) and thermal stability of beta alloy. Heat treatment of beta 


alloy plastic excellent in quenching condition, and the tensile strength of 130~140kgf/mm2 by aging 


treatment. Beta alloys are used for high strength and high toughness materials. The disadvantage is heavy, 


high cost, poor welding performance, difficult machining.

stable carbide with high hardness. The growth of the carbonization layer between titanium and carbon is 


determined by the diffusion rate of titanium in the carbonization layer.



The solubility of carbon in titanium, in 850X: total is 0.3%, and at 600C about down to 0.1%B due to the 


small size of the solubility of carbon in titanium, so basically only through the deposition of titanium carbide 


layer and below call domain layer to surface hardening of the objective. Must be carried out under the 


conditions of the removal of oxygen carburizing, as applicable to common carburizing steel powder against 


carbon monoxide or surface of carbon monoxide in the oxygen bearing and the formation of surface layer


 hardness reaches 2700MPa and 8500MPa, and. Very easy to peel.


Compared with this, the deoxidation or decarburization conditions in charcoal carburizing may form a thin


 layer of titanium carbide. The hardness of this layer is 32OUOMPa, which is in conformity with the 


hardness of titanium carbide. The depth of the carburizing layer is more than the depth of the nitriding layer 


under the same conditions. Under the condition of oxygen enrichment, the absorption of oxygen must be 


taken into account to influence the depth of hardening. Only in a very thin layer thickness, in vacuum or 


argon methane atmosphere permeability toner can form sufficient adhesion strength compared with this, the


 gas carburizing agent may be particularly hard and good adhesion of the titanium carbide hardening layer 


is formed. At the same time, the hardening of the 950T: and 10201: is formed between the 50fim and the 


hardening. With the increase of the layer thickness, the titanium carbide layer becomes more brittle, and tend 

to be from peeling off t in order to avoid due to decomposition of the Rui alkane and carbon inclusions 


invasion of titanium carbide layer, using about volume fraction for Rui alkane 2% of the prescribed dose 


additive in inert gas in gas carburizing. The lower surface hardness is formed when the methane is used as a


 propane additive. When the adhesive Wu Lida to Mao OkPa conditions in the use of propane gas 


carburizing, although measured the thickness of hardened layer is very thin, but has the best wear resistance.


 In the use of gas carburizing agent under the conditions of hydrogen absorption, but in vacuum annealing 


but had to re remove it.
