摘要
近年来,随着铝基复合材料(aluminum matrix composites, AMCs)常规力学性能研究不断深入与发展,室温力学性能已经取得突破性进展,并在航空航天装备等领域得到应用。然而,在高温环境下,AMCs长时间服役后以蠕变损伤的形式发生宏观失效,且微观组织对蠕变损伤的影响尚不明晰。因此,结合AMCs增强相具有设计多样性的优势,调控增强相种类、含量、尺寸、界面结合强度、构型设计等参数是优化其抗高温蠕变性能的关键策略。为了深入理解AMCs的蠕变机制并分析提高抗高温蠕变性能的未来发展趋势,本文重点综述了AMCs的蠕变变形行为和高温蠕变性能,讨论了具有潜力的材料制备策略,可为抗高温蠕变AMCs的设计与研发提供指导。
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.
