Topic: Unlocking superior properties in ultra-high temperature ceramics: Spark plasma sintering and unconventional additives
Details
Spark Plasma Sintering (SPS) enables the rapid fabrication of Ultra-High Temperature Ceramics (UHTCs) with enhanced properties by incorporating unconventional additives traditionally used in various fields. Materials such as MAX phases, high-entropy alloys (HEAs), and g-C₃N₄, originally developed for catalysis, structural alloys, and electronics, are being repurposed by our group as sintering additives to improve densification, microstructure, and mechanical properties of UHTCs. This talk will present how these novel additives, when integrated into UHTC matrix composites and processed by SPS, transform them into advanced materials capable of enduring extreme environments. With promising applications in aerospace, abrasive, and energy sectors, SPS, combined with innovative additives, is redefining the performance boundaries of ceramics.
Speaker
Dr. Mehdi Shahedi Asl is an Associate Professor at Xi'an Jiaotong-Liverpool University (XJTLU), China, with a Ph.D. in Materials Engineering from the University of Tabriz, Iran. His academic journey began in 1999 with a bachelor’s in Metallurgical Engineering at Iran University of Science and Technology, followed by a master’s at Sharif University of Technology. In 2015, he completed his Ph.D. and started his career as an Assistant Professor at the University of Mohaghegh Ardabili. In 2020, he undertook a postdoctoral fellowship at the University of New Brunswick, Canada, focusing on advanced materials research. From 2022 to 2024, he served as an Associate Professor at the University of Kyrenia, Cyprus, before joining XJTLU in July 2024. With over 220 SCI papers and being recognized as a top-cited scientist (2% list published by Stanford University and Elsevier) for five consecutive years, his work continues to make a significant impact in ceramics and advanced materials.
