Titanium


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.


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 di al, 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).

Supply specifications of titanium tube


Supply specifications of titanium tube: diameter less than 4~114mm thickness Delta 0.2~4.5mm length 15m


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 components. The current aircraft engine 


components, skeleton, skin, 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.

Edit this paragraph Taisi folding carburizing surface treatment


Titanium wire forms a 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.
