Roles of Yttrium and Zirconium Additions in High-Temperature Oxidation Resistance of Al0.7CoCrFeNi High-Entropy Alloys

Influence of overheating exposure time on the microstructural stability and mechanical properties of HP40-0.63Nb alloy

HP40-Nb heat-resistant cast steels are widely used for reformer furnace tubes operating at elevated temperatures, where accidental overheating may induce microstructural degradation and alter mechanical properties. This study investigates the influence of overheating time on the microstructure and mechanical properties...

Effect of Molten-Salt Chemistry on Phase Evolution and Corrosion Degradation of Sc2O3-Y2O3 Co-Stabilized ZrO2 Thermal Barrier Ceramics

The corrosion resistance of electron-beam physical vapor-deposited (EB-PVD) zirconia thermal-barrier coatings depends on ceramic phase stability. Here, conventional 8YSZ and two Sc2O3-Y2O3 co-stabilized ZrO2 coatings, ScYSZ and ScYSZ with an Al-rich interlayer (ScYSZA), were comparatively investigated under three chlor...

Wear Response of Carbide-Reinforced 1.75 mol% Y2O3-Stabilized ZrO2 Composites Under Dry Sliding Conditions

This study investigates the mechanical and tribological behavior of three composites with a ZrO2 matrix stabilized with 1.75 mol% Y2O3 and containing 1 wt.% Al2O3, reinforced with TiC (A), TiC + ZrC (B), and TiC + WC + Mo2C (C). The matrix powder was synthesized by chemical coprecipitation, and the composites were cons...

Effect of Mo Content on the Microstructure and Properties of FeCoCrNiMox High-Entropy Alloy Coatings Prepared by High-Velocity Oxy-Fuel Spraying

High-entropy alloy coatings (HEA) were applied to key components such as cutting tools, molds, and valves. In this research, FeCoCrNiMox high-entropy alloy coatings were deposited on 45 steel substrates using high-velocity oxy-fuel (HVOF) spraying. The influence of molybdenum (Mo) content on the coating properties was...

Effect of AlCrFeCuNi High-Entropy Alloy Reinforcement with a Nanocrystalline Internal Structure on the Microstructure, Electrical Conductivity and Tribological Behavior of SPS-Processed Cu–B4C Composites

This study investigates the effect of mechanically alloyed AlCrFeCuNi high-entropy alloy (HEA) reinforcement with a nanocrystalline internal structure on the microstructural, mechanical, electrical, and tribological properties of Cu–1 wt.% B4C composites containing 0–30 wt.% HEA. The AlCrFeCuNi reinforcement used in th...
