||This symposium focuses on new fundamental research advances and technological progress in the development, understanding, processing, and applications of refractory metals, which are defined as metallic elements with melting temperatures exceeding 2123 K (1850 C). Refractory metals are of great importance due to their excellent mechanical, microstructural, and chemical stability at high temperatures under extreme loading conditions. We invite submissions on a wide range of topics including alloy development, microstructural evolution, evaluation and correlation of properties, novel processing methods, and characterization techniques relevant for refractory metals. We encourage both experimental and theoretical work from academic, government, and industrial sectors to promote a diverse group of presentations from professionals and students. In addition, presentations on the use or applications of refractory metals and their alloys in energy, transportation, and other sectors are welcome.
