摘　　要：金属层片结构材料通过构筑不同力学特性的层片单元形成一种独特的层片异构材料,这种多维度和多尺度的异构特性可以诱导产生多种强塑性协同机制,以此实现材料强度-塑性的协同提升。材料制备手段和处理工艺的多样化丰富了层片结构的微观形貌,同时对层片结构的微观设计也不断提出了新的设计要求和准则。优化层片结构的设计并探索宏观力学行为与微纳米层片之间的关联不仅有利于建立金属层片结构材料的设计理论,还将推动该种结构材料的实际工程应用。本文综述了近年来国内外关于金属层片结构材料的研究进展,详细介绍了不同种类的金属层片结构及其力学性能和强塑性机制,最后对层片结构未来的研究趋势和面临的挑战进行了简单的展望。Lamellar metallic materials comprising lamella units with different mechanical properties can form a unique lamellar heterostructured material.The heterostructures could induce various strength-ductility synergetic mechanisms due to the action of multi-type and multi-scale heterogeneity.Multiple lamellar morphologies have emerged with the diversification of material preparation means and processing treatments,and thus new requirements and design criteria have been derived for optimizing the lamellar microstructure.Optimizing the microstructural lamellar design and exploring the relation between mechanical behavior and micro/nano-lamellar structures will not only contribute to establishing the design theory about laminated metallic materials,but also accelerate its practical application.In this paper,the research progress on laminated metallic materials in recent years was reviewed.Classification of metallic lamellar structures,their mechanical properties and strength-ductility mechanisms were introduced and discussed in detail.Finally,perspectives on the future research trends and challenges of lamellar structures were briefly stated.
