| Abstract Scope |
In-depth understanding of phase evolution and grain refinement mechanisms under additive manufacturing conditions is the foundation for predicting and controlling microstructures in as-printed parts. This talk will present our recent results on using in-situ high-speed synchrotron X-ray diffraction and imaging to uncover the dynamics of phase transformation and grain structure evolution during rapid heating and cooling. The mechanisms of non-equilibrium material transformation behavior, including melting, dissolution, precipitation, solidification and grain structure evolution will be discussed. |
