氮對灰鑄鐵初生奧氏體析出溫度的影響

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

摘要: 用差熱分析的方法測定了氮對Fe^-C_3.45^-Si_2.15和Fe^-C_3.45^-Si_2.15^-Mn_0.80灰鑄鐵初生奧氏體析出溫度的影響,并運用熱力學原理對實驗結果進行了討論。

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.
