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。
The effect of nitrogen on the precipitation of primary austenite in Fe-C_ (3.45) ~ -Si_ (2.15) and Fe ~ C_ (3.45) ~ -Si_ (2.15) ~ -Mn_ (0.80) gray cast iron was investigated by differential thermal analysis The influence of temperature, and the use of thermodynamic principles of the experimental results were discussed.
