Effect of FeCoNiMoW high entropy alloy binders on mechanical properties of high entropy (Ti,W,Mo,Nb,Ta)(C,N) based cermets

Fenmo yejin jishu
Conventional Ti(C,N)-based cermets predominantly utilize Co/Ni as the bonding phase. This study explores the preparation of high-entropy (Ti,W,Mo,Nb,Ta)(C,N)-based cermets by vacuum sintering, utilizing high-entropy (Ti,W,Mo,Nb,Ta)(C,N) ceramics as the ...

Ultrafast CO2 Laser Sintering of Nonwetting Alumina–Iron Ceramic–Metal Composites

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Alumina–iron composites are attractive for structural and functional applications but are difficult to consolidate because molten Fe poorly wets Al2O3, promoting capillary‐driven segregation during conventional liquid‐phase sintering. Here, we show that ultrafast nonequilibrium CO2 laser sintering enables rapid consolidation of this unstable ...

In Situ Sintering Studies of Reactive Sintered Borides (RSB) Neutron Shielding Materials

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT Reactive sintered borides (RSBs) are a family of radiation‐dense materials made by powder metal processing and sintering of elemental precursors. Recent interest in RSBs has focused on their properties as high‐flux low‐activation thermal neutron absorbers for nuclear applications including fusion reactors.
