摘要:
复合化是金属材料实现高性能化的有效途径，但传统的金属基复合材料多以相与组织在空间的均匀分布为特征，没有充分考虑到材料的复合构型效应，因此不能最大程度地发挥不同组分之间的协同、耦合和多功能响应机制。近年来，国内外的材料科学家逐渐认识到复合构型(architecture)对于金属基复合材料强韧化的重要作用，并进行了一些探索研究，发现“非均匀”复合构型更有利于发挥复合设计的自由度和复合材料中不同组元间的协同耦合效应，从而发掘金属基复合材料的性能潜力。本文首先综述了金属材料构型复合化的研究进展，进而以复合构型的优化设计为切入点，提出可以通过借鉴生物结构材料中的精细复合构型，来制备具有优异综合力学性能的金属基复合材料。该研究理念在石墨烯-铝(Al)，碳纳米管-Al等材料体系中得到了验证，所制备出的复合材料具有良好的强度与塑性/韧性匹配。最后，本文展望了金属材料构型复合化的发展趋势，指出可采用先进的微纳米尺度测量技术结合显微结构表征的方法，以准确揭示非均匀复合结构的性能响应机理，阐明其构-效关系，为复合构型的进一步优化设计与精确“剪裁”提供途径与方法。
Abstract:
An effective way to improve the properties and performance of metallic materials is to form metal matrix composites (MMCs). However, traditional MMCs are characterized by a uniform spatial distribution of constituent phases and microstructures, which is unfavourable to fully take advantage of the synergistic, coupling, reinforcing effects, and multi-functional response mechanisms from the different phases of the composites. In recent years, materials scientists throughout the world have gradually realized the importance of microstructural architecture for the improvement of the overall mechanical properties of metal matrix composites, where studies show that nonuniform architectures are more favorable to take full advantage of the coupling effect of the constituent phases and subsequently realize their reinforcing potential for various properties of the composites. In this paper, the development of the architectured MMCs was reviewed first, and it was proposed that the delicate architectures in hard biological materials may inspire the design of advanced MMCs with superior properties. This concept has been verified in graphene-aluminum (Al) and carbon nanotube (CNT)-Al composite systems, where the composites were shown to have significantly enhanced mechanical properties than the unreinforced matrix materials, and have a balanced strength-ductility/toughness synergy. Before closing the discussion, this paper overviewed the perspective of architectured MMCs and proposed that, by using state-of-art micro-/nano-scaled characterization tools combined with site-specific microstructural analysis, the deformation mechanism and the? property-structure correlation can be pinpointed, leading to improved design and tailoring of architectured MMCs.
