摘要
Possibility of abnormal grain growth (AGG) is vital when tuning grain structure of polycrystalline materials. The growth stability of a particle-pinned polycrystalline aggregation is discussed. It is mathematically proved that in such aggregation, Hillert's steady-state normal grain growth assumption is stable against arbitrary perturbation; hence, AGG is impossible as long as pinning is uniform. This conclusion is independent of the detailed pinning mechanism, evolution of pinning strength, or the dimension of the system.
