| This is because the single-phase evolution of polycrystalline system, the driving force of grain from the system interface can be reduced, and the second phase particles at grain boundaries can reduce the interface, so when the circular second phase particles occupy the intersection of the three crystals, rod-like second-phase particles in the direction of the grain boundary and grain boundary in the same direction, the system reduces the size of the largest grain boundaries, the system interface to the minimum, consistent with trends in the evolution of the system. |
