Abstract

Heterogeneous lamella (HL) structures were produced via simple processing steps in a FeCoNi-based complex concentrated alloy (CCA) with superalloy-like FCC/L12 microstructure. Compared to the homogeneous-structured control specimens, the HL-structured specimens exhibited synergic enhancements in strengths and ductility (with σy up to 1 GPa, σu up to 1.4 GPa, and ϵt up to 16.5%), and at the same time, higher saturation magnetization and lower coercivity (with Ms up to 104 Am2 kg−1 and Hc 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. GRAPHICAL ABSTRACT IMPACT STATEMENT The current work presents a simple and effective strategy that can be applied to soft magnetic alloys with superalloy-like microstructures for simultaneous enhancements of mechanical and magnetic properties.

通过类高温合金软磁复合浓缩合金中的非均匀片层结构同时改善机械和磁性能

通过简单的工艺步骤，在具有类似高温合金FCC/L12微观结构的FeCoNi基复合浓缩合金（CCA）中制备了非均匀片层（HL）结构。与均匀结构的对照试样相比，HL结构的试样在强度和延展性方面表现出协同增强（σy高达1 GPa，σu高达1.4 GPa，和高达16.5%的εt），同时具有更高的饱和磁化强度和更低的矫顽力（Ms高达104 Am2 kg−1，Hc低至833 A/m）。本研究中获得的结果为在不牺牲磁性能的情况下提高结构软磁材料的机械性能提供了见解。图形摘要影响声明当前的工作提出了一种简单有效的策略，可应用于具有类似高温合金微观结构的软磁合金，以同时提高机械和磁性能。
