Abstract Scope |
This talk explores a newly developed Monte Carlo-based grain evolution code designed to model the annealing of structural metals. The code is an adaptation of the classical curvature-driven Potts model that includes both pinning particles and dislocation density as driving forces. The model parameters were than specifically tuned to emulate the annealing of additively manufactured Inconel 718 using several sets of experimental results as ground truth experiments. Furthermore, this model has been built within the popular open source SPPARKS framework, allowing for the quick adaption and implementation by anyone interested in replicating this functionality. |
