Distribution of Phosphorus in Cast Iron
-
摘要: 利用 Auger 表面分析和化學分析等手段,研究了鑄鐵中磷在鐵/石墨界面上的偏析及在鐵相與石墨兩相間的分配。實驗結果表明,磷在球鐵中有界面偏析現象,而在灰鐵中沒有發現偏析。磷在球鐵和灰鐵中的偏析特點正與硫在這兩類鑄鐵中的偏析特點相反。Abstract: Studied with AES and chemical analyses, the distribution of phosphorus was found to be different between nodular iron and grey iron. Phosphorus atoms segregate at iron/graphite interface in nodular iron, while the interfaces in grey iron are free of phosphorus. Such different behavior of phosphorus between nodular iron and grey iron is opposite to that of sulphur.
