Abstract Scope |
A combination of Calphad-based computational tools is applied to study the microstructure evolution during additive manufacturing (AM) of steels. The computational investigations are integrated with advanced materials characterization techniques for model validation and calibration with the goal to develop a computational framework for AM steel design. Examples of our ongoing research activities will be presented with focus on the solidification behavior, solid-state phase transformation and precipitation kinetics during laser- or electron beam-powder bed fusion and post-process heat treatment of martensitic hot-work tool steels. |
