Decomposition process in a FeAuPd alloy nanostructured by severe plastic deformation

, 2008
The decomposition process mechanisms have been investigated in a Fe50Au25Pd25 (at.%) alloy processed by severe plastic deformation. Phases were characterized by X-ray diffraction and microstructures were observed using transmission electron microscopy ...

Ultrahigh‐Strength Soft‐Magnetic NiFeCoAl Multi‐Principal Element Alloys Enabled by Multiscale Heterostructure Design

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Soft‐magnetic materials (SMMs) are indispensable for electrification and sustainable energy systems, yet their inherent mechanical fragility fundamentally limits applications under severe mechanical stresses. Enhancing the yield strength of SMMs is essential to prevent the degradation in magnetic performance and failure from plastic ...

Tailoring Differentiated Multiscale Microstructure to Enhance the Mechanical Properties of Additively Manufactured AlCoFeNi2 at Room and High Temperatures via Annealing

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Additively manufactured AlCoFeNi series eutectic high‐entropy alloys (EHEAs) exhibit nonequilibrium dual‐phase microstructure in the as‐printed state, allowing them to be easily tailored through annealing to explore their strength–toughness potential.
