Titanium can quickly react and gas

Liquid and solid titanium can not react, not combined with aqua regia could not reach it, however, titanium gas is very hit it off, like with nitrogen, oxygen, hydrogen, carbon dioxide, water vapor, methane and many other gases combined. This feature can produce titanium magical for us to use.
     You do not have more than one night to enjoy the colorful fireworks festival over it? Here there is a credit titanium. When combined with titanium powder and oxygen to burn quickly, and be able to produce a strong heat and glory. Fireworks can not only enhance the festive atmosphere at the festival, but also as a military flares, used to indicate the target or convey orders. In the arc lamp in the added amount of the grade 2 titanium forged ring compound, can increase its brightness. Using titanium strong absorption of air, the air can be removed, creating a vacuum. For example, the use of a vacuum pump made of powdered metal suppliers, you can put the air pumped only 1,000 million million. In the metallurgical industry, plus a small amount of titanium to steel or other metals, the "eat" inside the gas and impurities, can play a very good addition to the role of nitrogen deoxygenation, but also to eliminate the harmful effects of sulfur, thereby improving the steel and other alloy mechanical properties, to improve their resistance to corrosion.

Titanium more for aviation

Approximately 80% of titanium production for the aviation and aerospace industries. Airframe structural materials such as the US B-1 bomber, the titanium about 21%, mainly used in the manufacture of the fuselage, wings, skin, and bearing components. Airframe structural materials F-15 fighter, the titanium alloy with a capacity of 7000kg, accounting for about 34% of the weight of the structure. Boeing 757 aircraft structural parts, Powder coating titanium or about 5%, with a capacity of 3640 kg. McDonnell Douglas / production company DC10 aircraft alloy with a capacity 5500kg, accounting for more than 10% of the weight of the structure. The amount of Titanium round barin the chemical and general engineering areas: United States accounts for about 15% of its production in Europe accounts for about 40%. Due to the excellent corrosion resistance of titanium and its alloys, good mechanical properties, as well as qualified histocompatibility, making it a prosthetic device for the production of biological materials

Titanium is a new structural material

Titanium is a new structural material, it has excellent performance, such as low density (4.5gcm-3), high specific strength and fracture toughness, fatigue strength and resistance to crack growth, good low-temperature toughness, corrosion resistance excellent, the maximum operating temperature of some titanium alloys for 550 / C, is expected to reach 700 / C. So it gets increasingly widely used in aviation, aerospace, chemical, shipbuilding and other industrial sectors, is developing rapidly. Light alloy, steel, etc. (σ0.2 / density) versus temperature, stronger than the titanium alloy is higher than other light metals, steel and nickel alloys, and this advantage can be maintained to 500 / C or so, so some titanium suitable for manufacturing gas turbine components.

The production of titanium and titanium military profile

Titanium has many obvious superior characteristics: density (4.5kg / m3), high melting point (1660 ℃), corrosion resistance, high strength, good plasticity, but also through alloying and heat treatment methods to produce high mechanical properties the variety of alloys, is an ideal material for aerospace engineering structures. With a certain amount of oxygen, nitrogen, carbon, silicon, iron and other elements α phase titanium impurities. Stamping process with excellent performance, good weldability, and heat treatment is not sensitive to the type of tissue has a certain strength at a satisfactory plasticity conditions. Commercially pure titanium content of impurity elements in accordance with the division level. Its main strength depends on the content of oxygen interstitial elements, nitrogen. It has a high corrosion resistance in sea water, but poor in mineral acid. Generally used for manufacturing at a temperature -253 ~ 350 ℃ work discontinuity large variety of sheet metal parts or forgings, can also be manufactured rivets, wire and tubing. Application examples: Industrial use of commercially pure titanium in addition to manufacturing parts, extensive use of titanium alloy. It gets in the aviation, aerospace, chemical, shipbuilding and other industries increasingly wide range of applications, gas turbine component manufacturing, production of biological materials such as prosthetic devices. The density of titanium is generally 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 structures can be made out of high unit strength, rigidity, lightweight parts and components. At present, aircraft engine components, skeleton, skin, so the use of titanium fasteners and landing gear.

The use of titanium in the military industry, primarily titanium and titanium alloys have excellent performance based on: (1) reduce the structural quality, improve structural efficiency. Tactical and technical performance requirements of advanced aircraft structure has a relatively low quality factor (ie, the quality of the body structure / aircraft normal takeoff weight), low density powdered metal suppliers alloy, high strength, instead of structural steel and high temperature alloys, can greatly reduce the structural quality. Heat resistance (2) meet the temperature requirements of a titanium alloy. Currently hot strength titanium alloy by alloying the maximum temperature up to 500 ° C ~ 600 ° C, the temperature structure of the Titanium Flange Screwalloy also use up to 300 ° C ~ 400 ° C, the TI-64V can be used at 350 ° C under the long-term work, not at the high temperature of the plane (such as the rear fuselage, etc.) can be replaced by high-temperature performance does not meet the requirements of aluminum, TC11 long-term work at 500 ° C under the engine compressor components can be replaced by high-temperature alloys and stainless steel. (3) can be matched to the composite structure. To reduce the structural quality and meet the requirements of stealth, advanced aircraft extensive use of composite materials, the strength of titanium and composite materials, better match the stiffness, can get a good weight loss, and because both potential closer, easy to produce electricity Galvanic corrosion. (4) excellent in corrosion resistance. Titanium tube fittings is more excellent than other metallic materials and corrosion resistance in neutral oxidizing atmosphere and many harsh environments, small extent constrained by environmental conditions.

Application of titanium in military

Titanium is the end of the Second World War desire 1940s to 1950s began with the industrial production and gradually developed a high-performance structural materials is important. Since the first application is to provide high-performance materials for military aviation industry. With the development of national military industry, applications are continuously expanding titanium. So far, grade 2 titanium forged ring has been more and more applications in the aerospace, nuclear, ships, weapons and many other areas, has become an important strategic metal. Its application level has also become a country of advanced weaponry extent, reflects the level of a country's military and military strength, an important measure.
