Morgan Trexler (second from left), program manager for Science of Extreme and Multifunctional Materials in APL’s Research and Exploratory Development Department, welcomed attendees and called for continued leadership in addressing the nation’s critical materials discovery needs.

, materials director for the Emerging Technologies Directorate, Advanced Materials Critical Technology Area, Office of the Under Secretary of Defense for Research and Engineering, introduced the challenges and opportunities facing the implementation of the Materials Genome Initiative for national security applications.

The National Security Challenges panel talked about the impacts of the Era of Great Power Competition on the U.S. materials science community and defense manufacturing. Further discussions focused on the competitive posture of the U.S. defense industrial base for global competition, advancing priorities to innovate defense manufacturing, and mitigating vulnerabilities to supply chains and industrial materials production. The panel then explored how accelerated materials discovery—alloy development and production, substitutions for critical minerals, materials for nuclear power and propulsion systems, energy storage, lunar manufacturing, materials for hypersonics, and more—is needed across the Navy, Department of Energy, NASA, and defense community. The panel also described national initiatives and strategic plans focused on advancing U.S. global competitiveness through accelerating materials solutions and utilizing AI and other solutions.

A critical step of the materials discovery process is predicting new material compositions, synthesis routes, microstructure formation, and resulting properties. The PREDICT panel addressed challenges, needs, and emerging technology advances with respect to data availability, generation and identification of candidate materials, and the ability to simulate and/or predict materials properties to ensure desired properties. Panelists discussed the importance of leveraging predictive models—built on physics-based methods and a multitude of AI approaches—for various stages in discovery ranging from theoretical to lab-scale synthesis to scalable manufacturing. They discussed impacts of innovations that are transforming the landscape and demonstrating great promise (e.g., rapid computation powered by graphics processing units [GPUs], edge computing and custom architectures, and new approaches for reconciling low- and high-fidelity data).
