层压金属复合材料（lmc）是一种独特的复合材料形式，其中交替的金属层或含金属层通过离散的界面粘合在一起。综述了这些材料的力学性能。描述了材料在低温和高温下的拉伸性能。在低温下，沉积加工的层压板可以获得很高的抗拉强度，而通过层厚细化，辊接层压板可以获得很高的抗拉延展性。在高温下，观察到超塑性，并与本构蠕变关系的预测一致。损伤临界性能（如断裂韧性、疲劳和冲击性能）和阻尼可以优于组件材料。损伤临界性能受到层界面局部脱层的强烈影响。已经提出了导致lmc许多独特性质的机制。叙述了加工工艺、层压板结构和微观结构对这些机理和性能的影响。
Laminated metal composites (LMCs) are a unique form of composite material in which alternating metal or metal containing layers are bonded together with discrete interfaces. The mechanical properties of these materials are reviewed. The tensile properties at low and high temperatures are described. At low temperature, very high tensile strengths can be achieved in deposition processed laminates and very high tensile ductilities can be achieved in roll bonded laminates by layer thickness refinement. At high temperature, superplasticity has been observed and agrees with predictions from constitutive creep relations. Damage critical properties (such as fracture toughness, fatigue, and impact behaviour) and damping can be superior to those exhibited by the component materials. The damage critical properties are strongly influenced by local delaminations at layer interfaces. Mechanisms responsible for many of the unique properties of LMCs have been proposed. The influence of processing, laminate architecture, and microstructure on these mechanisms and properties are described.
