High-Entropy Alloys and Oxides for Structural, Catalytic, and Energy Applications
This community investigates the synthesis, microstructure, and mechanical properties of materials containing multiple principal elements, specifically high-entropy alloys and oxides. The work focuses on achieving specific combinations of strength, ductility, corrosion resistance, and catalytic activity for use in structural components, energy storage, and electrocatalysis.
The research is dominated by the study of high-entropy alloys (HEAs) and high-entropy oxides, with a strong emphasis on refractory variants. Recurring themes include the manipulation of microstructure and grain boundaries to optimize strength-ductility synergy, the development of corrosion-resistant coatings, and the application of these materials in hydrogen storage and electrocatalysis. Methodologies frequently cited include spark plasma sintering, mechanical alloying, and machine learning for phase prediction and design. The community also explores medium-entropy alloys and complex concentrated solid solutions, often targeting elevated-temperature stability and oxidation resistance.
The largest share of the community's output is found in hydrogen research, accounting for 0.1% of all hydrogen research, and 423 papers here. The community also contributes significantly to carbon and oxygen research, with 397 and 374 papers respectively, representing 0.0% and 0.1% of their respective element research.
The community comprises 6,096 papers, with the most frequent publication venues being the Journal of Alloys and Compounds, Acta Materialia, and Metals. Recent work continues to focus on the synthesis of refractory high-entropy alloys, the design of corrosion-resistant cobalt-based systems, and the application of machine learning to predict phase stability in high-entropy carbide ceramics.
