Abstract: 

This presentation will discuss the current use of advanced manufacturing techniques and tools to design and create new material solutions for extreme environments.  This includes the use of machine learning and advanced characterization systems to capture critical microstructure and chemical features controlling material response.  Oak Ridge National Laboratory has world-class capabilities and facilities targeting the integration of computational and experimental tools, including neutron diffraction, atom probe tomography, and super-computing capabilities.  Resulting projects involve the development of high temperature complex concentrated alloys, ceramic materials,  light weight structural alloys, and functionalized interfaces.  Key aspects of the research involve capturing relevant kinetic processing information and understanding phase evolution mechanisms at the appropriate length and time scales.
