Single-crystal FeCoNiMn high-entropy alloys with exceptional topological Hall properties

Microstructure-Controlled Magnetic Properties of Annealed FeCo Nanowires: The Key Role of Crystallinity and Defects

The magnetic properties of FeCo nanowires are determined by their microstructure. By annealing as-deposited nanowires in reductive and oxidative atmospheres, we obtain two distinct microstructural states: a highly crystalline FeCo alloy phase and a CoFe 2 O 4 spinel phase derived from complete transformation of...

Tailoring the microstructure and magnetic properties of FeCoMnAlSi high-entropy alloys: the role of Al/Si content and annealing treatment

Processing, Microstructural Evolution and Engineering Performance of High-Entropy Alloys: A Review

High-entropy alloys (HEAs) and multi-principal-element alloys (MPEAs) provide broad compositional flexibility for regulating phase stability, microstructure, and properties. However, nominal composition and average phase constitution alone are insufficient to describe the actual material state formed during processing...

Kinetic control preserves the single-phase fcc structures of CuPdAgPtxAu high-entropy alloy nanoparticles.

High-entropy alloy nanoparticles (HEA NPs) constitute a promising class of materials for heterogeneous electro- and thermal catalysis due to their exceptional compositional tunability. However, precise structural control remains a challenge-particularly for quinary systems, where composition and structure are often int...

A Comprehensive Review of Bridgman Solidification of High-Entropy Alloys

Conventional casting of high-entropy alloys was constrained by multi-principal element solidification behavior and was prone to severe grain boundary segregation and microstructural inhomogeneity, limiting their service performance in extreme environments. Bridgman directional solidification can help to achieve oriente...
