Large Time Asymptotic Behavior Of Grain Boundaries Motion With Dynamic Lattice Misorientations And With Triple Junctions Drag

Many technologically useful materials are polycrystals composed of a myriad of small monocrystalline grains separated by grain boundaries. Dynamics of grain boundaries play an essential role in defining the material's properties across multiple scales. In this work, we study the large-time asymptotic behavior of the model for the motion of grain boundaries with the dynamic lattice misorientations and the triple junctions drag.
