Abstract Scope |
The evolution of the structure of the Grain Boundary network (GBN) during grain growth strongly influences material properties. Historical modeling efforts considered isotropic interface properties. However, it has been shown that anisotropic boundary properties affect grain growth. More recent computational studies of grain growth have considered anisotropy in the context of simplified models for which GB energy depends only on lattice misorientation (e.g. using a Read-Shockley model). In this talk, we present results of fully anisotropic grain growth simulations (based on level set methods) in three dimensions. Fully 5D grain boundary energy anisotropy is considered, using a recently developed GB energy model that considers all five GB crystallographic degrees of freedom. We characterize the global structure of the GB network using a recent spectral decomposition technique. The present work shows how anisotropic interfaces energies influence the evolution of the spectrum of the GB network during grain growth. |
