Second, the technical requirements for titanium and titanium alloy chemical composition of the cake should be consistent with the provisions of GB / T3620.1, and when the demand side reinspection, tolerance hundred Yung Titanium chemical components comply with GB / T3620.2 three, titanium and titanium performance titanium alloy tube is a new type of metal, titanium and carbon contained in the performance of impurity content of nitrogen, hydrogen, oxygen, etc., and the most pure titanium iodide impurity content of not more than 0.1%, but its low strength, high ductility. 99.5% of the performance of industrial pure titanium as: density ρ = 4.5g / cm3, a melting point of 1725 ℃, thermal conductivity λ = 15.24W / (mK), the tensile strength σb = 539MPa, elongation δ = 25%, reduction of area rate ψ = 25%, the elastic modulus E = 1.078 × 105MPa, the hardness HB195. (1) high-strength titanium alloys than the average density of about 4.5g / cm3, only 60% of steel, titanium's strength was close to the strength of ordinary steel, some high-strength titanium alloy structural strength than a lot of steel. Therefore, the ratio of titanium strength (strength / density) is much larger than other metal structural materials, see Table 7-1, the unit can be made out of high strength, rigidity, lightweight parts and components. At present, aircraft engine components, skeleton, skin, so the use of titanium fasteners and landing gear. (2) the use of high temperature hot strength of several hundred degrees higher than aluminum, at moderate temperatures can still maintain the desired strength, long-term working range of these two types of titanium alloys at 150 ℃ ~ 500 ℃ at a temperature of 450 ~ 500 ℃ inside is still very high specific strength, while aluminum fell significantly at 150 ℃ when strength. Titanium alloy operating temperature up to 500 ℃, the aluminum alloy is below 200 ℃. (3) good corrosion resistance of titanium alloy in humid atmosphere and seawater, which is far superior corrosion resistance of stainless steel; for pitting, etching, stress corrosion resistance is particularly strong; alkali, chloride, chlorine organic materials, nitric acid, sulfuric acid, etc. have excellent corrosion resistance. However, the corrosion resistance of titanium with a reduction of oxygen and chromium salts medium is poor. (4) good low temperature performance at low temperatures and titanium ultra-low temperature, retains its mechanical properties. Low temperature performance, low interstitial elements of titanium, as TA7, at -253 ℃ still maintain a certain plasticity. Thus, low-temperature titanium alloy is also an important structural materials. (5) chemical activity of large chemical activity of titanium is large, a strong chemical reaction with atmospheric O, N, H, CO, CO2, water vapor, ammonia and the like. Carbon content greater than 0.2%, it will form a hard TiC in the titanium alloy; at higher temperatures, and also the role of N forms TiN hard surface; at above 600 ℃, the high hardness of hardened layer is formed of titanium absorbs oxygen ; hydrogen content increased, brittle layer will form. Absorbing gas produced brittle surface to a depth of 0.1 ~ 0.15 mm, the degree of hardening of 20% to 30%. Chemical affinity of titanium is also large, easy and sticking friction surface. (6) small thermal conductivity, the elastic modulus of the small thermal conductivity of titanium λ = 15.24W / (mK) of about 1/4 of nickel, iron 1/5, 1/14 aluminum, and various thermally conductive titanium alloy coefficient of thermal conductivity than that of titanium by approximately 50%. Elastic modulus was about 1/2 of the titanium alloy for steel, so the poor rigidity, deformation, and should not be made thin-walled elongated rod member, the machined surface when cutting a large amount of spring back, the stainless steel is about 2 to 3 times, causing severe tool flank friction, adhesion, adhesive wear. Fourth, the main use of titanium alloy tube has high strength and density and small, good mechanical properties, good toughness and corrosion resistance. In addition, poor process performance titanium alloy, machining difficulties in thermal processing, and very easy to absorb carbon hydrogen nitrogen and other impurities. There are poor abrasion resistance, complex production process. Titanium industrial production was started in 1948. Require the development of the aviation industry, the titanium industry with an average annual growth rate of about 8% of the development. Currently the world's titanium alloy production reached 40,000 tons, nearly 30 kinds of titanium alloys. The most widely used titanium alloy is Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and commercially pure titanium (TA1, TA2 and TA3). Titanium tube light weight, high strength, excellent mechanical properties, corrosion resistance is excellent. It GF used: aerospace, ships, auto parts, bicycle parts, marine engineering desalination, aquaculture, offshore oil drilling, water pipes; power industry in OTEC power plants, condensers, steam The chlor-alkali chemical petroleum industry, soda ash, urea, as well as vacuum salt petrochemicals;; metallurgical industry electrolysis, electroplating; light in the textile, paper, fuel; medical medical industry equipment maker human substitute titanium turbine blade joints ; Manufacture of sports equipment, daily life computers, cameras, watches, glasses, cell phones, kitchen utensils, and crafts; architectural decoration industry.
