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…
Kinetic and Equilibrium Shapes of Cylindrical Grain Boundaries
Anqi Qiu, Caihao Qiu, Ian Chesser +3
In this work, we investigate the shape evolution of rotated, embedded, initially cylindrical grains (with [001] cylinder axis) in Ni under an applied synthetic driving force via mo…
Disconnection Flow-Mediated Grain Rotation
Caihao Qiu, Marco Salvalaglio, David J. Srolovitz +1
Interface migration in microstructures is mediated by the motion of line defects with step and dislocation character, i.e., disconnections. We propose a continuum model for arbitra…
Interface Faceting-Defaceting Mediated by Disconnections
Caihao Qiu, Marco Salvalaglio, David J. Srolovitz +1
An intrinsic feature of nearly all internal interfaces in crystalline systems (homo- and hetero-phase) is the presence of disconnections (topological line defects constrained to th…
