ABSTRACT The pre‐existing α‐Fe crystals have important effects on the precipitation and growth of nanocrystals and finally determine the comprehensive soft magnetic properties (SMPs) of the nanocrystalline alloys (NAs). In this work, a high content of Cu elements has been added to Nanomet‐type alloys to enhance the gradient heterogeneity in order to ...

Influence of Surface Nanocrystallization on Two-Step Pack-Boronizing of AISI 5120 Steel
AISI 5120 steel, which underwent 30 min single-surface nanocrystallization via supersonic fine particle bombarding (SFPB), was pre-boronized at 600 °C for 2 h, and then final-boronized at 800 °C or 900 °C for 2–6 h, i.e., two-step pack ...

Direct Observation of Matrix‐to‐Precipitate Elemental Diffusion in Severe Plastic Deformation
ABSTRACT Elemental redistribution, particularly the solute exchange between the matrix and precipitates, is a central issue in alloys subjected to severe plastic deformation (SPD). To elucidate this behavior, a nickel–aluminum bronze (NAB) alloy was processed by high‐pressure torsion (HPT), and its microstructural evolution was systematically ...

ABSTRACT The inherent trade‐off between high saturation induction (Bs) and low core loss in soft magnetic materials presents a challenge in the development of high‐frequency power electronics. Here, a processing approach that combines accelerated Cu ordering with dual magnetic anisotropy control in high‐Bs Fe‐based nanostructured cores is examined ...
