用俄歇能谱仪探测重轨钢中磷的分布。试验结果表明,磷的晶界偏聚是在冷却过程中形成的,冷速慢有利于磷的偏聚。
Using Auger spectroscopy to detect the distribution of phosphorus in heavy rail steel. The experimental results show that the segregation of the grain boundaries of phosphorus is formed during the cooling process, and the slow cooling rate is favorable for the segregation of phosphorus.
