Development history of titanium industry

Release time : 2022-07--06 点击量 : 223
Summary: In 1791, the English priest W. Gregor discovered a new metal element in black magnetite. In 1795, the German chemist M.H. klaproth also discovered this element when studying rutile, and named it after the Greek god Titans. In 1910, American scientist M.A. Hunter first reduced tici with sodium to produce pure titanium. In 1940, Luxembourg scientist W.J. Kroll reduced TiCl with magnesium to produce pure titanium. Since then, magnesium reduction method (also known as Kroll Method) and sodium reduction method (also known as hunter method) have become industrial methods for the production of sponge titanium. In 1948, the United States produced 2T sponge titanium by magnesium reduction method, which has reached the scale of industrial production since then. Subsequently, Britain, Japan, the former Soviet Union and China also successively entered industrial production, of which the major titanium producing countries were the former Soviet Union, Japan and the United States. Titanium is a new metal. Because of its series of excellent characteristics, it is widely used in industrial production such as aviation, aerospace, chemical industry, petroleum, metallurgy, light industry, electric power, seawater desalination, ships and daily life appliances. It is known as a modern metal. Titanium production has a history of only half a century since 1948. It is a new industry developed with the aviation and aerospace industry. Its development has experienced several ups and downs because titanium is related to the aircraft manufacturing industry. But in general, the development speed of titanium is very fast, which is faster than that of any other non-ferrous metals. This can be seen from the development of sponge titanium industry in the world: the production scale of sponge titanium was 60kt/a in the 1960s, 1lokt/a in the 1970s, 130kt/a in the 1980s, and reached 140kt/a by 1992. The actual output reached a record high of 105kt / A in 1990. After entering the 1990s, the market was weak in previous years due to the reduction of military titanium and the selling of sponge titanium stocks in some countries such as Russia. In 1995, the titanium market began to rebound, mainly due to the substantial increase in the amount of civil titanium such as B777 and golf clubs. In 1996, the demand for titanium reached a new high. Experts predict that the demand for titanium will continue to increase significantly in the next few years. At present, the main reason hindering the application of titanium is its high price. It can be expected that with the progress of science and technology and the continuous improvement of titanium production process, expanding the production capacity of enterprises, improving the management level, and further reducing the cost of titanium products, it is bound to open up a broader titanium market.

Ten properties of titanium

Release time : 2022-07--06 点击量 : 400
Summary: Low density and high specific strength The density of titanium is 4.51g/cm3, which is higher than that of aluminum but lower than that of steel, copper and nickel, but its specific strength ranks first among metals. Corrosion resistance Titanium is a very active metal, its equilibrium potential is very low, and its thermodynamic corrosion tendency in the medium is large. But in fact, titanium is very stable in many media. For example, titanium is corrosion-resistant in oxidizing, neutral and weak reducing media. This is because titanium has a great affinity with oxygen. In air or oxygen-containing medium, a dense, adhesive and inert oxide film is formed on the surface of titanium, which protects the titanium matrix from corrosion. Even due to mechanical wear, it will soon self heal or regenerate. This indicates that titanium is a metal with strong passivation tendency. When the medium temperature is below 315 ℃, the oxide film of titanium always maintains this characteristic. In order to improve the corrosion resistance of titanium, surface treatment technologies such as oxidation, electroplating, plasma spraying, ion nitriding, ion implantation and laser treatment have been developed to enhance the protection of titanium oxide film and obtain the desired corrosion resistance effect. In order to meet the needs of metal materials in the production of sulfuric acid, hydrochloric acid, methylamine solution, high-temperature wet chlorine and high-temperature chloride, a series of corrosion-resistant titanium alloys such as titanium molybdenum, titanium palladium and titanium molybdenum nickel have been developed. Ti-32 molybdenum alloy is used in titanium castings, ti-0.3 mo-0.8 nickel alloy is used in the environment where crevice corrosion or pitting corrosion often occurs, or ti-0.2 palladium alloy is used locally in titanium equipment, which has achieved good application results. Good heat resistance The new titanium alloy can be used for a long time at 600 ℃ or higher. Good low temperature resistance Titanium alloys TA7 (ti-5al-2.5sn), TC4 (Ti-6Al-4V) and ti-2.5zr-1.5mo are low temperature titanium alloys, whose strength increases with the decrease of temperature, but the plasticity changes little. It maintains good ductility and toughness at -196-253 ℃ and avoids the cold brittleness of metal. It is an ideal material for low-temperature containers, tanks and other equipment. Strong damping resistance Compared with steel and copper, titanium has the longest vibration attenuation time after mechanical and electrical vibration. This property of titanium can be used as tuning fork, vibrating element of ultrasonic crusher in medicine and vibrating film of advanced sound loudspeaker. Non magnetic and non-toxic Titanium is a non-magnetic metal, which will not be magnetized in a large magnetic field. It is non-toxic and has good compatibility with human tissue and blood, so it is adopted by the medical community. The tensile strength is close to its yield strength This property of titanium shows that its yield strength ratio (tensile strength / yield strength) is high, which indicates that the plastic deformation of titanium material is poor during forming. Because the ratio of yield limit to elastic modulus of titanium is large, the resilience of titanium during forming is large. Good heat exchange performance Although the thermal conductivity of titanium metal is lower than that of carbon steel and copper, the wall thickness can be greatly reduced due to the excellent corrosion resistance of titanium. Moreover, the heat exchange mode between the surface and steam is drop condensation, which reduces the heat group. If there is no scaling on the surface, the thermal resistance can be reduced, and the heat exchange performance of titanium can be significantly improved. Low elastic modulus The elastic modulus of titanium is 106.4gmpa at room temperature, which is 57% of that of steel. Inspiratory performance Titanium is a metal with very active chemical properties, which can react with many elements and compounds at high temperature. Titanium gettering mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature.
