摘要

本文提出了一种利用Cu-Fe的不混相性来构建FCC/FCC双相结构的策略。双相结构和l12纳米沉淀物实现了多尺度协同强化,显著提高了强度。同时,所有相干低能界面显著降低了应力局部化,保证了非常小的延性牺牲率。

Enhancing the mechanical properties of multi-principal element alloys via constructing dual-heterostructures through the immiscibility between elements
A strategy utilizing the immiscibility of Cu-Fe to construct FCC/FCC dual-phase structures was proposed in this work. The dual-phase structure and L12-nanoprecipitates achieve multi-scale synergistic strengthening, significantly improving the strength. Meanwhile, all coherent low-energy interfaces significantly reduce stress localization, and ensure a very small ductility sacrifice rate.
