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 largetime asymptotic behavior of the model for the motion of grain boundaries with the dynamic lattice misorientations and the triple junctions drag.

具有动态晶格错误取向和三重结阻力的晶界运动的大时间渐近行为

许多技术上有用的材料是由无数被晶界隔开的小单晶晶粒组成的多晶。晶界动力学在定义材料在多个尺度上的特性方面起着至关重要的作用。在这项工作中，我们研究了具有动态晶格错误取向和三重结阻力的晶界运动模型的大时间渐近行为。
