titanium alloy for aerospace industry

Titanium alloy titanium cn is widely used in the aerospace industry and other industrial sectors. With the rapid development of science and technology progress and our national economy, as the "great rise of the third generation of metal titanium industry will".

The characteristics and application of titanium alloys for Aerospace

As the rise of aerospace materials, titanium alloy has the following advantages:

(1) high strength ratio. Titanium alloy with very high strength, the tensile strength is 686~1176MPa, and the density is only about 60% of steel, so the intensity ratio is very high.

(2) excellent high temperature performance. Titanium alloy can still keep good mechanical properties at high temperature, its heat resistance is much higher than that of aluminum alloy, and a wide operating temperature range.

(3) the corrosion resistance. At 550 ℃ in air, the titanium surface will form a thin and compact titanium oxide film, its corrosion resistance is better than that of most stainless steel.

In the aviation industry, titanium alloy is mainly used in the manufacture of jet engine compressor disk, disk, blades, casing, as well as large main landing gear support beam, the rear section and the steering beam structure. Because the titanium alloy has high specific strength and high temperature characteristics, used in the manufacture of aircraft engine and airframe can effectively improve the engine thrust weight ratio and the mechanism efficiency, help to alleviate thermal phenomena in many aerospace applications, titanium and its alloys are replacing the traditional aluminum alloy. Now, titanium materials aerospace industry consumption accounts for about 42% of total global production, and from now to 2010, is expected to titanium materials demand will continue to grow at a rate of two digit. A new generation of aircraft need to fully utilize the performance of titanium alloy provided, whether commercial or military aircraft market, are pushing demand on titanium alloy. The Boeing 787, the Airbus A380, the F-22 Raptor fighter, the F-35 Joint Strike Fighter (also known as the lightning II) and other new models have used a lot of titanium alloy material. Current situation of machining titanium alloys for Aerospace

In order to meet the growing of the titanium alloy processing aviation manufacturing industry demand, manufacturers need to increase production capacity, so we need to better understand the effectiveness of titanium alloy processing strategy. Machining of titanium alloy workpiece typical is from forging began, until the 80% material is removed to obtain the final shape of workpiece.

With the rapid growth of aviation parts market, manufacturers have to feel powerless, processing requirements and for titanium alloy machining efficiency is low and increased, leading to the titanium alloy processing ability is obviously in a state of tension. Some aviation manufacturing leader even publicly questioned the processing task machining capability of existing can complete all the new titanium alloy workpiece. Because these parts are made of new type alloy, so we need to change the way of processing and cutting tool materials.
