High-Throughput Computational Guided Development of Refractory Complex Concentrated Alloys-based Composite
Project Innovation + Advantages:
West Virginia University seeks to commercialize alloys and manufacturing processes to improve the overall safety, energy efficiency, and environmental performance of air travel and electricity generation. The team will develop a new class of ultra-high temperature refractory complex concentrated alloys-based composites (RCCC) for high temperature applications such as combustion turbines used in the aerospace and energy industries. The approach is based on a transformative “high-entropy” strategy. The RCCC will consist of Refractory Complex Concentrated Alloys (RCCA) mixed with nanosized particles of refractory high entropy carbides, to increase RCCA strength to withstand extreme conditions. The goal is to optimize the balance among strength, creep (deformation), density, and stability at 1300 °C , while maintaining ductility once the alloy cools to room temperature. The research team will develop a specialty 3-D metal printing process to produce test coupons and potentially components such as turbine blades.
Combining development of new ultrahigh temperature materials with compatible coatings and manufacturing technologies has the potential to increase gas turbine efficiency up to 7%, which will significantly reduce wasted energy and carbon emissions.
