Abstract:
In recent years, with the deepening and development of research on the conventional mechanical properties of aluminum matrix composites (AMCs), room temperature mechanical properties have made breakthroughs and are used in aerospace equipment and other fields. However, in high temperature environments, creep damage is the main form of macroscopic failure of AMCs after long-term service, and the effect of microstructure on creep damage is not clear. Therefore, combined with the advantages of the diversity of composite reinforcement design, adjusting the type, content, size, interfacial bonding strength, architecture design and other parameters is a key strategy to improve the creep resistance of AMCs. To analyse the development trend that can improve the creep resistance of AMCs and understand the creep mechanism, this paper summarizes the creep deformation behaviours and the influence and mechanism of creep properties at high temperatures and discusses potential material fabrication strategies, which can provide guidance for the design and development of high-temperature creep resistant AMCs.
