Abstract:The development of next generation aero engines requires support of advanced materials and appropriate new structures and technologies. According to the service environment of aero materials,some points of view on combining the structure concept with material concept,the advancement and reliability of aero engines with the controllability and safety of structure and defect for research and development of materials are proposed. From the aspects of fundamental properties of maximam service temperature,high temperature specific strength,antioxidation,toughness,conductivity and processing ability,the behaviour of traditional and new materials systems is analysed and some suggesstions aimed at the problems in development of aero engine materials in China are presented.
Keywords:Material for aero  engine  superalloy  ceramic matrix composite  intermetallic compound material
