Original Title: Brief Introduction to Titanium Alloy and Titanium Plate Summation of domestic and foreign materials of nickel-based superalloy Titanium is a chemical element, chemical symbol Ti, atomic number 22. It is a silvery white transition metal characterized by light weight, high strength, metallic luster, and good corrosion resistance (including seawater, aqua regia, and chlorine gas). Because of its stable chemical properties, it has good resistance to high temperature, low temperature, strong acid and alkali, as well as high strength and low density. Titanium is a new type of metal. The properties of titanium are related to the content of impurities such as carbon, nitrogen,titanium round bar, hydrogen and oxygen. The impurity content of the purest titanium iodide is not more than 0.1%, but its strength is low and its plasticity is high. The properties of 99.5% industrial pure titanium are as follows: density ρ = 4.5g/cm3, melting point 1725 , thermal conductivity λ = 15.24W/ (m. K), tensile strength σb = 539MPa, elongation δ = 25%,titanium exhaust tubing, reduction of area ψ = 25%, elastic modulus E = 1.078 × 105MPa, and hardness HB 195. Titanium and its alloys are widely used in aviation industry, known as "space metal", and are increasingly widely used in shipbuilding industry, chemical industry, manufacturing of mechanical parts, telecommunications equipment, hard alloy and so on. In addition, titanium plate gr7 ,nickel titanium wire, because the titanium alloy has good compatibility with the human body, the titanium alloy can also be used as an artificial bone. There are two executive standards for titanium plate, GB/T3621-2007 and GB/T13810-2007, and ASTM B265, ASTM F136, ASTM F67 and AMS4928. The grades are divided into the following types: American standard: GR1, GR2, GR3, GR5, GR7, GR12; Russian label: BT1-00, BT1-0, BT1-2, etc.; Domestic brands: TA0, TA2, TA3, TA5, TA6, TA7, TA9, TA10, TB2, TC1, TC2, TC3, TC4. Hot working state (R), cold working state (Y), annealed state (M). Titanium plate manufacturing process: Hot forging a forging process performed above the recrystallization temperature of the metal. Hot rolling The process of rolling above the recrystallization temperature. Cold rolling: Rolling process in which the temperature of plastic deformation is lower than the recovery temperature. "Annealing: Heat treatment of metals by slow heating to a temperature, holding for a sufficient time, and then cooling at a suitable rate, usually slowly, sometimes in a controlled manner.". Pickling: Immerse the workpiece in an aqueous solution of sulfuric acid,titanium filler rod, etc. To remove the oxide film on the metal surface. It is the pretreatment or intermediate treatment of electroplating, enameling, rolling and other processes. Return to Sohu to see more Responsible Editor:. yunchtitanium.com
