Abstract A topologically heterogeneous microstructure design is introduced in a Cu/Zr nanolayered composite, in which each soft 100 nm Cu or Zr layer is surrounded on both sides by several hard 10 nm Cu/Zr bilayers. This design aims to impose a full geometrical constraint on all of the soft layers. Micropillar compression tests demonstrate that the composite deforms in a compatible fashion among the layers, in which no extrusion of the soft layers occurs. An elevated strength of 730 MPa is achieved in the composite compared with the strength prediction based on the linear rule of mixtures.

异质纳米层复合材料的相容变形和额外强化

摘要 在 Cu/Zr 纳米层复合材料中引入了拓扑异质微结构设计，其中每个软的 100 nm Cu 或 Zr 层的两侧都被几个硬的 10 nm Cu/Zr 双层包围。该设计旨在对所有软层施加完整的几何约束。微柱压缩试验表明，复合材料在各层之间以相容的方式变形，其中没有发生软层的挤压。与基于混合物线性规则的强度预测相比，复合材料的强度提高了 730 MPa。
