摘要
磷元素在钢中的晶界偏聚可以分为两类,即平衡偏聚和非平衡偏聚。介绍了这两类偏聚现象以及偏聚理论。以磷对晶界结合力、晶界扩散和晶界能的影响机理为基础,分析了磷元素对钢力学性能的影响和磷在钢中发生晶界偏聚的原因。
The segregation of phosphorus on steel grain boundaries can be divided into two categories, which are, equilibrium segregation and non--equilibrium segregation. The segregatlion and its mechanism are reviewed in this paper, The effects of phosphorus on mechanical performance of steel are analyzed on the baiis of the influence mechanism of phosphorus on grain boundary cohesive force, grain boundary diffusion and grain boundary energy. The factors influencing phosphorus segregation on steel grain boundaries are also stated.
