Abstract Scope |
Solidification kinetics and non-equilibrium phase formation in the semi-solid state governs the properties of components produced by a vast range of processes from thin slab cooling to additive manufacting. Many of the modelling techniques used to simulate these processes are based on the work done over the past 50 years by Jon Dantzig, ranging from the macroscopic, to microstructural to atomistic level. This talk will look at methods of validating models of the non-equilibrium solidification kinetics across the length scales during additive manufacturing. Where appropriate, correlations of the techniques used to those developed by Jon will be made, both in terms of simulation and experimental validation, ranging from his formulating dimensionless numbers to predict equilibrium vs non-equilibrium conditions to his reviews of the best flash x-ray diffraction techniques to use to capture transient phase changes. |
