| Abstract Scope |
Accelerating discovery and scale-up of wear-resistant steels requires an integrated paradigm that connects AI, simulation, high-throughput experimentation, data infrastructure, and manufacturing feedback. This talk explores a closed-loop materials discovery workflow developed first for resource-constrained lunar in situ resource utilization and now extended to terrestrial wear-resistant alloy design. The workflow links knowledgebase-driven material selection, generative AI, physics-based simulation, additive manufacturing, multimodal characterization, and iterative predict-make-measure learning. Our campaigns have explored manufacturable composition spaces for wear-resistant steels under resource and processability constraints, emphasizing rapid downselection, validation, and translation toward scalable manufacturing. Rather than treating discovery and manufacturing as sequential steps, the approach incorporates manufacturability, additive processing constraints, composition-processing-microstructure-property relationships, and characterization feedback from the outset. We demonstrate how this approach enables materials discovery through iterative optimization of chemistry, processing, and microstructure for improved wear performance while building reusable infrastructure for accelerated innovation under real-world constraints. |
