Laser directed energy deposition of AISI 316L: Process, microstructures, and mechanical properties

This thesis conducted a comprehensive study on laser directed energy deposition of AISI 316L. Several key issues in laser directed energy deposition process were delicately studied, including oxidation, deposition efficiency, microstructural evolution, quasi-static and dynamic mechanical properties of the deposited materials, and digital twinning for additive manufacturing. This thesis focuses on frontier technologies in the field and contributes original knowledge to the pool of additive manufacturing. The research content and results obtained in this thesis advances the theoretical understanding of additive manufacturing technology for 316 stainless steel and provides significant guidance for its practical applications.
