Titanium alloy has low density, high specific strength, using wide temperature range (269 ~ 269 ℃), corrosion resistant, low damping and weldable, and many other advantages, is lightweight and improve the comprehensive performance of the aerospace craft the best material, its application level is embodies advanced craft level of an important aspect. It is an important measure to promote the application of titanium alloy in aerospace field to improve the comprehensive mechanical properties of aircraft and reduce the cost.
With the development of aerospace technology, the titanium alloy in the field of aerospace, expanded the application scope of titanium alloy structure is becoming more and more large size, thin-walled curved surface, variable thickness and the trend of overall structure, further improve the performance of the aerospace craft, the structure rigidity, reduced the weight, titanium alloy precision forming technology is the research focus of aerospace manufacturing technology.
Precision forming is refers to the parts close to or reached after forming parts precision forming technology, it is based on the new material, new equipment, new technology, and computer aided process design and technological achievements, on the basis of the development of the traditional forming technology, realize the high efficiency, high performance, low cost less WuYuLiang manufacturing technology, precision forming parts with high geometric accuracy and surface roughness, the appearance of precise and excellent mechanical properties. Titanium alloy precision forming technology is widely used in the field of aerospace, and its application can significantly improve the comprehensive performance and support ability of various types of combat aircraft, aero-engines, strategic and tactical missiles, carrier rockets and other aerospace products. For precision forming technology in hot forming/diffusion bonding (including precision casting, speeding forming, precision spinning) and laser direct rapid forming technology progress carries on the analysis of application of these technologies can realize the near net shape manufacturing, material utilization rate is as high as 70% ~ 90%, has been in the field of aerospace highlights the broad prospects for development and good application value.
