Fabrication‐Driven Oxidation Pathways in Y/Hf‐Modified High‐Entropy Alloys: From Elemental Segregation to Oxide Homogeneity

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and

Multicomponent Rare‐Earth Monosilicate Reactions With Calcium‐Magnesium Aluminosilicate

Journal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT High‐temperature reactions of multicomponent rare‐earth monosilicates (REMS) with calcium‐magnesium aluminosilicate (CMAS) were investigated at 1300°C for 24 h. Three compositional series were tested, each ranging from 1‐cation to 4‐cation REMS, with cations selected to interrogate compositional effects on CMAS reactivity. The final members of

Oxidation Performance of NiCoCrAlYTa + 7YSZ Coatings With Ta Addition at Different Temperatures

Rare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT This study investigates the morphology and oxidation behavior of thermally grown oxides (TGO) formed at the interface of NiCoCrAlYTa + 7YSZ (7 wt% Y2O3‐stabilized zirconia) coatings deposited by air plasma spray (APS) in air environments at 1050°C, 1100°C, and 1150°C. The enrichment of Ta‐rich oxides beneath the TGO, along with the segregation
