Understanding Subsurface Behavior and Defect Formation During Laser Material Interactions Via Coupled In Situ X-Ray and Optical Probes

Executive Summary

This project will use in situ x-ray experiments paired with optical monitoring to improve our understanding of subsurface materials behavior during laser materials processing techniques. This understanding will improve these techniques and enable rapid, science-based qualification of parts produced by laser materials processing, solving important challenges for both stockpile stewardship and American industrial competitiveness.
