Abstract Scope |
Additive Manufacturing of structural alloys represents a processing regime involving small melt pools, and rapid heating and cooling rates that lead to unique solidification microstructures and microstructures arising from subsequent solid-state transformations in structural alloys. This talk will focus on the ongoing developments in mesoscale modeling at the Oak Ridge National Laboratory through the Exascale Computing Project, ExaAM. The phase field simulations make use of an in-house developed code MEUMAPPS that takes advantage of the state-of-the-art, high performance computing platforms to carry out high fidelity, three-dimensional simulations of solidification and solid-state transformation in structural alloys such as Ti-6Al-4V, and Ni-base alloys 781 and 625. Simulations are compared with measurements performed in AM processed materials. Research performed at ORNL under contract DE-AC05-00OR22725 and supported by the Exascale Computing Project 17-SC-20-SC, and the Advanced Manufacturing Office through the HPC for Manufacturing Program at the Department of Energy. |
