摘要
本文综述作者近几年来关于溶质原子非平衡晶界偏聚热力学、动力学以及晶界平衡偏聚与非平衡偏聚之间关系的理论、实验研究工作。这些研究工作内容丰富,已达世界水平。它们为改善现有材料的力学性能以及发现新材料提供了理论依据。
In years of late,the authors have been engaged in the theoretical and experimental studies on the relationship between the non-equilibrium segregation of solute atoms at the grain boundaries as re- gards the thermodynamics,the kinetics relevant to this segregation;and the equilibrium segregation at the grain boundaries.Some of the findings provide theoretical basis for the materials in use to enhance and new materials to produce.
