| Abstract Scope |
Metallic alloys with complex chemistries and hierarchical microstructures are increasingly utilized in extreme aerospace and energy environments, where both high performance and in-situ repairability are essential. This study investigates the fundamental mechanisms of impact-induced bonding in oxide dispersion-strengthened (ODS) GRX-810 additively manufactured (AM) alloys. A high-throughput laser-induced micro-ballistic platform, integrated with high-speed imaging, is employed to probe high-velocity microparticle impacts while systematically varying particle size, target temperature, and material condition (ODS vs. non-ODS). Critical bonding velocities are quantified to inform solid-state additive repair strategies. The platform enables rapid data generation to train machine learning models that predict bonding behavior across a wide process-structure space. By coupling high-throughput experimentation with data-driven modeling, we reveal deformation and bonding mechanisms operative at extreme strain rates and provide a predictive framework for alloy design and qualification. These findings advance the development of resilient, repairable high-temperature structural materials for next-generation aerospace and energy applications. |
