Grain Growth Simulations
Curvature-Driven Grain Growth (Secondary recrystallization)
Driving force: Reduce total grain boundary energy
The larger grains will grow at the expense of smaller grains.
Modeling: 3D Monte-Carlo Simulation
Visualization: Paraview (XMDF+HDF5 files)
Bicrystal: Spherical grain inside the matrix (larger grain)
Bicrystal: Spherical grain inside the matrix (larger grain)
The diameter of the spherical grain reduces uniformly in all the directions
Bicrystals: Cubical grain inside the matrix (larger grain)
Bicrystals: Cubical grain inside the matrix (larger grain)
The corners of the cubical grain are disappearing first.
Eventually, it converts to the spherical grain
Polycrystals
Polycrystals
Stored energy-driven grain growth
Driving force: Stored energy during plastic deformation prior to annealing
The smaller defect free grains (nucleation) will grow at the expense of neighboring grains
