Abstract

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.

通过元素间的不混相形成双异质结构来提高多主元素合金的力学性能

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。
