The meeting was organized by Beijing Aeronautical Manufacturing Technology Research Institute, China Aviation Technology Development Corporation I,ugg milano, China Institute of superplastic forging of professional committees and the professional branch of China Aviation Institute of Technology co. From the Navy,stivali ugg, Air Force, aviation, aerospace, weapons and other defense industries, universities, research institutes and materials production units in more than 5O nearly 120 representatives attended the meeting, the meeting also invited the French company engaged in the ACB superplastic forming technology experts to do the report. The meeting is the second in November 1999 held in Hangzhou, \\Conference on \development \China in recent years to demonstrate the new progress titanium forming, superplasticity, and new breakthroughs in theoretical research on the application of the new achievements, reflecting titanium superplastic forming technology and research has strong, showing that the titanium alloy and super plastic forming technology in defense weapons and equipment that has a good prospect. Adoption of the report and exchange, the participating experts and scholars on the current and superplastic forming technology of titanium alloy, some of the problems reached the following consensus: 1. With titanium hot forming, super plastic forming structure gradually increased the amount of aircraft, industrial design departments should organize and process units together to create the design specifications and process-related standards for the technology application and reduce the structural design create the conditions for the validation costs. 2. High temperature, high strength, lightweight materials and non-ideal superplastic deformation mechanism of superplastic materials research is the development of new materials based on deformation processing, attention must be fully and closely combined with the application. 3. Need to further strengthen research and application of superplasticity in international exchange and cooperation, further improve China's international research and applications of superplastic influence and status. The meeting was forming technology of titanium alloy, superplasticity theoretical and experimental exploration of titanium superplastic forming technology and other aspects of an event, for tracking the international advanced level, improve our titanium superplastic forming technology and research and theory design level,ugg stivali, to strengthen domestic different units in different fields in the titanium superplastic forming technology and materials research and application of the cooperation will have a profound impact.
