Abstract Scope |
Additive manufacturing (AM) is significantly expanding the design space of structural alloy components through its ability to build-in geometrical features that are impossible through traditional manufacturing methods. However, because of the extreme thermal histories experienced during AM, it is necessary to design new alloy compositions that not only allow defect-free processing, but also exploit the AM processing conditions to promote unique microstructures to meet target properties. This research will highlight high-resolution, three-dimensional phase-field simulations of solidification microstructure development during AM of novel titanium alloys with emphasis on consistently achieving columnar-to-equiaxed transition (CET) to promote fine equiaxed grain structure formation throughout a component with complex geometrical features. Research sponsored by the Advanced Manufacturing Office of the U.S. Department of Energy under the High-Performance Computing for Energy Innovation (HPC4EI) program and performed at the Oak Ridge National Laboratory managed by UT-Battelle, LLC, under Contract No. DE-AC05-00OR22725 for the U.S. Department of Energy. |
