摘要

Abstract

Heterogeneous lamella (HL) structures were produced via simple processing steps in a FeCoNi-based complex concentrated alloy (CCA) with superalloy-like FCC/L1

microstructure. Compared to the homogeneous-structured control specimens

the HL-structured specimens exhibited synergic enhancements in strengths and ductility (with σ

up to 1 GPa

up to 1.4 GPa

and ϵ

up to 16.5%)

and at the same time

higher saturation magnetization and lower coercivity (with M

up to 104 Am

−1

and H

as low as 833 A/m). The results obtained in this study provide insights to enhancing mechanical properties in structural soft magnetic materials without sacrificing their magnetic properties.
