Aviation materials belong to knowledge intensive and technology intensive disciplines. Many facts have shown that it is difficult to meet the increasingly high requirements of modern aviation technology by solely relying on traditional processes and technologies to change material composition. Therefore, countries attach great importance to the development and application of new technologies and processes in the field of aviation materials, which has promoted the development of aviation materials. The new technologies and processes applied and developed by various countries in the development of aviation materials mainly include directional solidification technology, mechanical alloying, rapid solidification, composite cutting technology, electron beam, plasma beam and laser beam technology, vacuum arc remelting, fine grain casting technology and corresponding development of hot isostatic pressing technology, superplastic forming technology, and solid-state welding technology.
