Explosively Formed way titanium steel composite panels and application characteristics

America in the 1960s began to produce titanium steel composite blasting materials, seminars 1980s success with titanium steel sandwich composite dairy law. Blow molding is the use of explosives, blasting high voltage pulse generator load direct role in the cover plate, cover plate so that within a few microseconds are accelerated to speeds of several hundred meters per second, the cover plate from the detonation end sequentially beginning with the substrate skew bump , the two pressure plates occurs bump greatly exceeds the dynamic limits of the metal bow, the occurrence of severe plastic deformation of the speed bump in the data area, accompanied by vigorous heat effect, the two metal plates similar to the bump surface layer of the fluid at the moment have the same action constitute two share movement in the opposite direction of the metal jet. Free bump point located in front of the jet ejection speed is not welded to the space, which washed away the two metals to be linked to form the mask, revealing a clean active surface metallurgy contact form under high pressure.

Advantages of a combination of blasting method is that a wide range of adaptability of information, such as different melting points, a large linear expansion coefficient and hardness of the molded material can be selected to produce a composite data burst. Greatly different linear expansion coefficients, such as titanium and stainless steel can be used to produce a composite sheet forming blasting. Blow-molded composite material selection can be made of two or more layers. Its drawback is the high production safety requirements can not be continuously produced only apply to certain materials.

Titanium steel composite board now has a variety of production methods, such as direct rolling, casting dairy France, blasting rolling method and blasting method. These approaches have been able to use a variety of thickness and width of the output specifications of the composite sheet. Titanium clad steel sheet substrate is generally carbon steel, structural steel or pressure vessel steel, titanium or titanium alloy cladding material, both with high strength, but also has excellent corrosion resistance of titanium, the use of the characteristics of each monomer materials, use a wide scale. Titanium steel composite panels can be made by a variety of hot and cold processing of industrial products, such as tube sheet heat exchanger, head, reactor, the reactor cylinder and containers. Titanium steel composite panels used in demand particularly suitable corrosion resistant equipment, which has been widely used in the manufacture of various metallurgical, chemical and marine industrial equipment.

Titanium in the course of development of China's aviation sector

In the field of aviation, the current consumption of titanium is only 10%, but with the start-up and implementation of China's large aircraft program, the Chinese titanium industry ushered in a dual high-end development of favorable policies and markets. Titanium application in the aviation field will usher in major development. During the "Eleventh Five-Year", China launched a large trunk aircraft project, who tied for civil aircraft industry in 2020 China's long-term plan, one hundred million yuan invested 50 billion -600 major projects development of large aircraft, large aircraft major projects set up by the State Council Leading Group has been completed, "large aircraft demonstration program report", with 13 years to develop its own mainline aircraft, and the establishment of a large trunk aircraft manufacturing company. China now has the ability to develop large trunk aircraft. In addition to the design capacity, in the course of cooperation with McDonnell Douglas MD90 in production, has already started to master the production and management capacity trunk aircraft. From the ARJ-21 start from, to do an exercise for the development of large aircraft.
