| Abstract Scope |
High-throughput measurement is a crucial approach for enhancing the number of measurements conducted in a shorter timeframe at synchrotron facilities. In our research, we have developed a methodology to deepen the understanding of selective laser melted maraging stainless steels by examining samples with varying printing parameters. Based on the collected data, created a physical model of precipitation that aims to advance computational materials design. These experiments are particularly challenging to conduct using slow laboratory-scale measurements, due to limited in-situ insights into the bulk material behavior. To address this, we employed in-situ high-throughput measurements during the heat treatment of both model alloys and multicomponent alloys. This approach will enhance the modeling of precipitation using the Langer-Schwartz-Kampmann-Wagner framework, as implemented in the TC-PRISMA software. Model ternary alloys will serve to calibrate the selection of model parameters for CALPHAD databases, while multicomponent alloys will be utilized for validation of the models. |
