从热力学角度来看，溶质在晶界偏聚，通过降低晶界能来降低晶粒长大的驱动力，从而抑制晶粒长大。从动力学角度来看，溶质与晶界交互作用，钉扎晶界，使晶界迁移速率降低，从而抑制晶粒长大。本文从热力学和动力学两方面综述了溶质对单相纳米晶材料晶粒长大行为的影响，并展望了其发展方向。
From the view of thermodynamics,grain growth was inhibited by reducing grain boundary energy and thus decreases the driving force through solute segregation.From the view of dynamic,grain growth was inhibi-ted by pinning grain boundary and thus decreases the mobility of the grain boundary through solute and grain boundary interaction.The effect of solute on grain growth behavior in single phase nanocrystalline materials by thermodynamic and kinetic approaches is reviewed in this paper,and the development direction is prospected.
