|This symposium provides a forum for the presentation of fundamental research advances and technological progress in the understanding, processing, and applications of refractory metals. Refractory metals are defined as those metallic elements with melting temperatures exceeding 2123 K (1850 °C). Refractory metals are of technological importance for their performance in extreme environments because of mechanical, microstructural, and chemical stability at high temperatures and under extreme loading conditions. Research of interest includes alloy development, microstructure evolution, and correlations with properties, both experimental and theoretical. Technological advances in processing of refractory metals and their alloys and applications in energy, transportation, and other sectors are also of interest.
New developments of interest include: refractory alloys with multiple principal components, C103 alloy replacements, and high throughput characterization of refractory materials, among others. Processing methodologies and techniques involving forming, welding, brazing, and powder metallurgy are also of interest. Presentations that communicate results from academia, national laboratories, and industry are welcomed. Presentations by students are highly encouraged.
A special session will be organized to focus on Ultrahigh Temperature Impervious Materials Advancing Turbine Efficiency (ULTIMATE). ULTIMATE is a program sponsored by ARPA-E that aims to develop a new class of ultrahigh temperature materials that can operate continuously at 1300 C or higher. Candidate materials include conventional refractory metal alloys and refractory high entropy alloys (RHEA). The program also covers coatings and manufacturing technologies necessary for these materials to succeed in power generation or jet engine applications. Relevant research from all contributors is welcome. Interested contributors, please indicate ULTIMATE in the abstract title.
