Design and Processing of High-Entropy Alloys by Powder Metallurgy for High-Temperature Applications<\/p>\n\n\n\n
High-entropy alloys (HEAs) exhibit high structural stability and exceptional resistance to oxidation and corrosion at elevated temperatures. This research focuses on the development of novel HEAs using powder metallurgy (PM) techniques to optimize their performance for future high-temperature structural applications. Both 3d-transition metal-based and refractory HEA systems were synthesized and comprehensively characterized using SEM, XRD, and TEM. The results highlight the importance of various parameters in predicting solid-solution formation and crystal structure. This study demonstrates that powder metallurgy is an effective approach for fabricating HEAs with tailored compositions and microstructures suitable for extreme environments, employing two main strategies: the incorporation of nano-oxides in BCC-structured HEAs and the promotion of Laves phase formation in refractory HEAs.<\/p>\n\n\n\n
Juan Cornide is assistant professor for Materials Science and Engineering at Complutense university, Madrid, Spain since 2022. Specialized in high entropy alloys (HEAs) and powder metallurgy. After completing his Ph.D. in materials science and technology, Dr. Cornide spent three years at Universit\u00e9 de Rouen as Post-doc, where he began exploring high entropy alloys and consolidated his expertise in microstructural characterization techniques. He then continued his academic career in Spain, at Carlos III University in the Powder Technologies Group. There, he led and contributed to several industrial projects focused on processing of different alloys for sintering and additive manufacturing technologies, particularly through powder metallurgy methods.\u00a0His work aims to design and produce high entropy alloys materials for high temperature applications, making them suitable for aerospace and energy applications. Dr. Cornide has published more than 30 papers on bainitic steels as well as HEAs, participated in international collaborations, and supervised students. His contributions have advanced the understanding of phase formation, and performance of different alloy systems fabricated through powder-based techniques.<\/p>\n","protected":false},"excerpt":{"rendered":"
