摘要:
叠层金属复合材料作为材料构型复合化的典型代表，在利用材料组元本征性能的基础上，能充分发挥复合材料中不同组元间的协同、耦合及多功能响应机制。微纳尺度下的叠层金属复合材料由于其多界面结构及特殊的尺寸效应，能充分调控材料内部裂纹的萌生与扩展机制,同时发挥微纳尺度材料优异的本征力学性能,以此来协调材料的强度和韧性的矛盾。目前，叠层金属复合材料在航天、石油、机械、电子等领域均得到了广泛的应用。围绕微纳叠层金属材料的断裂性能研究，综述了其制备工艺和应用现状，总结了其断裂过程中的微观机制和影响因素。同时，探讨了这类材料中特殊的构型化增韧途径，指出可采用先进的微纳米尺度的材料加工与测试技术，结合原位显微结构表征的方法，系统地研究微纳叠层金属材料的断裂机理，以指导对该材料的进一步优化设计与制备
Abstract:
Laminated metal composites are a typical representative of composites having microstructural architectures. These materials not only make full use of the intrinsic properties of the individual constituent phases, but also take advantage of the synergistic, coupling, reinforcing effects, and the multifunctional response mechanisms of the different phases. Metallic laminates with repeat layer thickness on the micro/nanoscale possess abundant interphase interfaces and are characterized by special sizedependent mechanical behaviors, so that balanced strength and toughness can be achieved by taking advantage of the excellent mechanical properties of the micro/nanoscale constituents, and by tailoring the crack initiation and propagation mechanism. Therefore, metallic micro and nanolaminates are widely used in aerospace, petroleum, machinery, and electronics industry. In this paper, the fracture properties of metallic micro/nanolaminates are reviewed, with particular focus on the microscopic mechanisms and influencing factors of fracture toughness. The fabrication processing and engineering application of these materials are also discussed, and critical microstructural parameters that affect their fracture toughness are identified. It is proposed that by using stateofart, micro/nanoscale characterization tools (such as in situ SEM/TEM and threedimensional atomic probe) combined with sitespecific microstructural analysis may provide important implications on the fracture mechanism of micro/nanolaminated metallic materials, leading to improved modeling and design of these materials.
