摘要：
Heterogeneous layered CuCrZr alloys with good interfacial bonding and excellent comprehensive properties were prepared by powder metallurgy combined with thermomechanical treatment. The fine-grained regions (FGR) and coarse-grained regions (CGR) are alternately distributed in the layered CuCrZr alloys. The superior combination of strength, ductility and electrical conductivity of the layered CuCrZr alloys is mainly attributed to hetero-deformation induced (HDI) strengthening contributed by the well-bonded layer interface during plastic deformation. The strengthening effect is caused by the accumulation of a large number of geometrically necessary dislocations (GNDs) at the heterogeneous interface, which induces extra work-hardening behavior and simultaneously enhances the strength and tensile ductility of the layered CuCrZr alloy. This work on heterogeneous layered CuCrZr alloys provides a new design strategy for overcoming the trade-off between strength, ductility and electrical conductivity in copper alloys.
