On the Formation of Micro-Shrinkage Porosities in Ductile Iron Cast Components
Metals, 2018 A combination of direct austempering after solidification (DAAS) treatment and electron backscatter diffraction (EBSD) method was used to study the formation of micro-shrinkage porosities in ductile iron.

Advanced Science, EarlyView.The interlayer magnetic couplings (left) and the changes of atomic‐layer‐averaged electron density (right) for Fe and Cu sides near the sharp and diffuse Fe/Cu (001) interfaces reveal that magnetic Friedel oscillations at Fe/Cu interfaces in steel drive atomic‐scale 2D alloying, resolving the long‐standing paradox of high Fe content in Cu precipitates.

Where Can Aluminum Go When Batteries Die?
Advanced Science, EarlyView.Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.

Tailoring Ni–Co–Mn–Sn Ribbons by Ge Doping for Enhanced Magnetocaloric Effect
Advanced Electronic Materials, EarlyView.Ni42Co8Mn39Sn11‐xGex (x = 1, 2 and 3) ribbons show tunable martensitic transformation and enhanced magnetocaloric performance through Ge substitution. Hysteresis is reduced with improved geometric compatibility between martensitic and austenitic phases, and the x = 2 sample exhibits an optimized magnetization change (ΔM) response, yielding an entropy ...
