The OpeN-AM experimental platform, installed at the VULCAN instrument at ORNL’s Spallation Neutron Source, features a robotic arm that prints layers of molten metal to create complex shapes. This allows scientists to study 3D printed welds microscopically. Credit: Jill Hemman, ORNL/U.S. Dept. of Energy

Microstructural Evolution Modeling

  • Bridging the gap between basic science and applied research for industrial applications:
    • Address the current needs of applied programs in understanding the atomic-level properties of basic research.
    • Develop multiscale approaches that seamlessly connect the nanoscale to macroscale.
    • Quantum applications, such as materials with multifunctional quantum properties
    • Electronic and magnetic materials for applied programs
  • Computational and theoretical design of functional/structural materials:
    • Structural materials and materials under extreme conditions for applied programs
    • Scalable microstructure simulation for additive manufacturing (ExaCA, OpenN-AM) and solidification processes
    • Nuclear materials
    • High-throughput approaches for ML/AI with predictable theory approaches
    • Multi-scale (time and spatial scales) approaches
