Influence of Competitive C–P Segregation on Austenite Grain Growth in Iron Alloys

steel research international, Volume 97, Issue 3, Page 1432-1443, March 2026.
This study investigates how carbon influences phosphorus‐induced solute drag effects during isothermal annealing of austenite grain growth in Fe–C–P alloys. Using in situ high‐temperature laser scanning confocal microscopy and density functional theory simulations, it demonstrates that carbon above a critical temperature significantly reduces P ...

Circular Alkali‐Activated Cements Based on EAF Slags and Biomass Bottom Ash Using Rice Husk Ash–Derived Sodium Silicate

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT This study investigates sodium silicate (SS) solutions derived from rice husk ash (RHA) dissolved in 8 M NaOH as sustainable activators for alkali‐activated cements (AACs), compared with commercial SS. AACs were produced using a 50:50 blend of electric arc furnace slag (EAFS) and biomass bottom ash (BA). The effects of NaOH/RHA ratio (6.6–2.8)
