| Abstract Scope |
Understanding and predicting the processing-structure-property (PSP) relationships in additively manufactured metals is required for both design and qualification of components. This study uses high-throughput (HT) synthesis and characterization techniques to establish the PSP relationship in laser powder bed fusion (LPBF) of stainless steel 316L (SS316L). Dimensional analysis yielded dimensionless relationships that were used to identify a high-fidelity process parameter range capable of achieving a relative density of 99%. Samples were fabricated in a high-throughput manner for the design of experiments covering a large process parameter range. The HT characterization framework used advanced surface and imaging techniques to create a microstructural database. Finally, HT indentation is used to generate a mechanical property database. The PSP relationship between process parameters, grain size distribution, crystallographic texture, cellular subgrain structures, and the mechanical properties of LPBF SS316L has been established by integrating these databases, thus providing processing, microstructure, and property maps of LPBF SS316L. |
