-
摘要: 铝基复合材料具有轻质、高强、高模量的优点，在航空航天、船舶、交通、3C 电子等领域得到了较为广泛应用，但随着科技的不断发展，现有的铝基复合材料已逐渐无法满足日益苛刻的使用要求，开发超高强度（屈服强度≥500MPa）的铝基复合材料迫在眉睫。本文系统总结了国内外先进超高强度铝基复合材料研究进展，简要介绍了超高强铝基复合材料基体选择，着重分析了增强体对其性能的影响，总结了超高强铝基复合材料变形加工工艺以及热处理工艺，并对其未来发展方向及面临的挑战进行了展望。Abstract: With the development of aerospace, shipbuilding, and 3C electronics, the performance requirements for materials used in components are increasingly stringent. Traditional aluminum matrix composites (AMCs) can not meet these demands. The development of ultra-high strength, high stiffness AMCs has become imperative. This review comprehensively summarizes the research advancements in ultra-high strength aluminum matrix composites worldwide, briefly introduces the selection of the AMC matrix, focuses on the impact of reinforcements on the performance, summarizes the deformation processing and heat treatment techniques for ultrahigh strength AMCs, and discusses the future development directions and challenges faced by these materials.
