| Abstract Scope |
Additive Manufacturing (AM) presents a highly complex process environment that demands a multiscale modeling approach to capture the interplay between thermal history, composition, and microstructure evolution. In this work, we employ a combination of computational thermodynamics and kinetics tools, with a focus on CALPHAD-based models, to predict critical microstructural features relevant to AM alloy development.
We explore how variations in composition and processing parameters influence phase selection during rapid solidification, micro-segregation, and solid-state transformations, including precipitation kinetics. Case studies involving both laser and electron beam-based AM processes are presented to illustrate the predictive capabilities - and current limitations - of these computational tools in capturing key phenomena during the processing of metallic materials. |
