Elliptical neutron‐focusing supermirrors with Ni–P‐plated Al–Si alloy substrates for multi‐incident‐angle neutron reflectometry

Journal of Applied Crystallography, Volume 59, Issue 5, Page 1509-1516, October 2026.
Multi‐incident‐angle neutron reflectometry is realized using elliptical metallic supermirrors for dual‐beam focusing. This approach presents new opportunities for efficient interface analysis.This study introduces a novel approach for multi‐incident‐angle neutron reflectometry utilizing metallic elliptical supermirrors to enable the simultaneous ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.
