Description

To improve the reproducibility of metallic additive manufacturing processes requires improved characterization and modeling techniques. This research will integrate a variety of modeling tools across multiple time and length scales. Some of these modeling tools include CALPHAD-based models, phase-field models, and finite-element models (FEM) to predict the microstructure evolution in metals-based additive manufacturing processes. This modeling will rely on a variety of characterization techniques to determine processing-structure-property relations that occur during processing. Some of the characterization techniques include scanning and transmission electron microscopy, thermal analysis, and x-ray diffraction techniques.
