| Abstract Scope |
Microstructure solidification in metal alloys is a complex multi-physics problem, where behaviours observed on the micro-level can often be instrumental in the formation of undesirable features and outright defects in the microstructure which can dictate the macroscopic material properties of the final parts. However, while experimental trends can be observed, full understanding of the transient interactions between physical processes at the microstructural level are not well understood. Numerical modelling offers an opportunity to explore effects which are often impractical to observe in experiments, however there is a paucity of existing numerical modelling that can account for both structural mechanical and fluid flow effects being resolved concurrently with solidification. The microstructure solidification code TESA has been expanded to incorporate the simultaneous resolution of these phenomena, allowing large-scale three-dimensional microstructure solidification simulations to be run which examine these interactions and demonstrate the impact they have on the morphology of the final microstructure. |
