Characteristics Of Titanium Alloy Sheet, Bar And Other Titanium Alloy Materials in The Field Of Aerospace Applications

Titanium alloy has small density, high strength and other excellent performance, is a more ideal aviation structure materials, at present titanium alloy in the aerospace industry application more and more by people's favor.

Titanium alloy has high tensile plasticity, can be welded in various ways, long time use temperature up to 250 degrees Celsius, mainly used to manufacture aircraft and engine on a variety of force is not big plate village structure parts. The new titanium alloy has a high tensile strength (800 degree Celsius lOOOMPa and good welding ability compared with丄 pure titanium, the new titanium alloy mainly includes various different grades of pure titanium and widely used Ti5Al2.5Sn titanium alloy. The new titanium alloy mainly includes various grades of pure titanium and widely used Ti5Al2.5Sn titanium alloy, the room temperature tensile strength of pure titanium fluctuates in the range of 350 degree Celsius and 700MPa. Ti5Al2.5Sn alloy has slightly lower process plasticity and higher thermal strength, and the long time working temperature can be as high as 450 degree Celsius.

With the rapid development of aviation, astronautics, nuclear energy and other science and technology, the requirements for materials are becoming more and more stringent, and not only do they require the materials used in the manufacture of these equipment parts to be resistant to corrosion, wear and vibration, but also to high temperatures. It is necessary to pay attention to the long time test, and in many places, the chemical industry before the large-scale application of titanium. In many cases, titanium is used in the chemical industry before it is used on a large scale. The service life and structure of the material are examined under test conditions. If the use of conventional structural materials is not economically viable due to the fact that most of them show a lack of safety (immaturity), it is necessary to gradually develop titanium and its alloys, as well as a variety of other new materials in the field of structural materials, which have been developed to a high level of technological maturity in the last few decades. For this reason, the field of application of titanium and its alloys in the military sector is developing faster than in the civilian sector.

In many industrial media, often the main rare earth metals and precious metals used to stabilize, or stainless steel and other materials to resist corrosion stress can only reach a certain limit, the majority of applications using titanium due to the small density, corrosion resistance and strength of the benefits. So far. In addition to the high consumption cost, titanium or titanium alloys can be used to obtain high corrosion resistance. The creep characteristics of hard titanium exceed those of aluminum and its alloys at temperatures exceeding 150 T. Considering that titanium alloys have unique creep characteristics under conditions of low density compared to other materials, we have found that the creep characteristics of hard titanium are superior to those of aluminum and its alloys. Characteristics of the advantages of hard titanium and found that the importance of the application of hard titanium in aircraft and missile manufacturing. Early application of titanium and titanium alloys in the field of aviation industry, recently due to the aviation industry more and more urgent need for high strength and low density materials and greatly promote the development of titanium manufacturing industry. the early 1950s, the United States in the aircraft on the triumphant application of titanium, although winch E plane only 1% of the structure of the weight of the titanium, but opened up the aviation industry to use titanium pioneering way. At present, the world's many high-speed aircraft are widely used titanium alloy as a structural material.

In the chemical industry and other applications of titanium or titanium alloy semi-finished products and processed parts are put forward very high requirements, so in the field of aviation and aerospace, the development of inspection instruments and monitoring devices is particularly expensive, so the price of titanium and gentile alloys parts have a great impact.
