High-Performance Materials focuses on structural and functional materials that will lower the cost and improve the performance of fossil-based power-generation systems. Computational tools to support predictive performance, failure mechanisms, and molecular design of materials are also under development to support highly focused efforts in material development.
Projects generally are initiated with a computational task to demonstrate a discovery and design methodology that is generally applicable to materials needed for the harsh environments of fossil-energy systems. This predictive computational framework accelerates the selection of materials for fossil-energy applications and utilizes multi-scale computational methods with focused validation experiments to predict alloy oxidation behavior in a variety of relevant environments. This activity involves the development of computational techniques for the virtual and rapid design of materials that show promise in satisfying the demanding requirements for advanced combustion systems. This research leads to alloy design and manufacture to provide specimens for demonstration of component life. The key High Performance Materials and Modeling objectives are:
