Shear-Coupled Grain Growth Statistics
Caihao Qiu, David J. Srolovitz, Gregory S. Rohrer +2
Grain growth (GG), driven by grain boundary (GB) migration, is a fundamental mechanism of microstructural evolution in polycrystalline materials. GB migration is frequently accompa…
Why Grain Growth is Not Curvature Flow
Caihao Qiu, David J. Srolovitz, Gregory S. Rohrer +2
Grain growth in polycrystals is traditionally considered a capillarity-driven process, where grain boundaries (GBs) migrate toward their centers of curvature (i.e., mean curvature…
Accurate grain boundary plane distributions for textured microstructures from stereological analysis of orthogonal two-dimensional electron backscatter diffraction orientation maps
Martin Folwarczny, Ao Li, Rushvi Shah +7
We present a method for obtaining qualitatively accurate grain boundary plane distributions (GBPD) for textured microstructures using a stereological calculation applied to two-dim…
Impact of grain boundary energy anisotropy on grain growth
S. Kiana Naghibzadeh, Zipeng Xu, David Kinderlehrer +3
A threshold dynamics model of grain growth that accounts for the anisotropy in the grain boundary energy has been used to simulate experimentally observed grain growth of polycryst…
