Grain-boundary kinetics: a unified approach

WebSep 16, 2024 · This phenomenon, known as grain growth, is governed by GB kinetics. Growing grains induce stresses on and experience complex interactions with nearby grains and defects. There are two types of grain growth: normal grain growth (NGG) and abnormal grain growth (AGG).
