氮对灰铸铁初生奥氏体析出温度的影响

Effect of Nitrogen on Phase Transformation Tempera-ture of Primary Austenite of Grey Cast Iron

摘要: 用差热分析的方法测定了氮对Fe^-C_3.45^-Si_2.15和Fe^-C_3.45^-Si_2.15^-Mn_0.80灰铸铁初生奥氏体析出温度的影响,并运用热力学原理对实验结果进行了讨论。

Abstract: Differential thermal analysis (DTA) tests were used to measure the effect of nitrogen on phase transformation temperature of primary austenite of Fe-C-Si and Fe-C-Si-Mn grey cast irons. The results were discussed with ther-modynamic theory.
