| Abstract Scope |
Given the vast processing space attainable through additive manufacturing, a trial-and-error approach to finding acceptable processing conditions is time-consuming and difficult for new alloys. Efficiently finding the optimal processing conditions that balance multiple considerations (e.g. minimize porosity and maximize yield strength) is even more difficult. In this presentation we discuss a simulation toolchain that combines thermal process simulations with analytic structure and property models to map standard laser powderbed fusion process parameters (e.g., power, velocity, hatch spacing, spot size) to common defects and mechanical properties. We demonstrate how this toolchain can be calibrated from simple single-track experiments and create process-structure-property maps for an example aluminum-copper-manganese-zirconium (ACMZ) alloy. Finally, we compare the predictions of the simulation toolchain to experimental characterization data for validation and discuss future research directions given these results. |
