The influence of nitrogen on the equilibrium and nonequi-librium phase transformation temperature of gray cast iron was studied by DTA and SDC methods with Fe-C-Si and Fe-C-Si-Mn alloys as experimental materials added with pure nitrogen.

• 本文采用工业纯Fe-C-Si和Fe-C-Si-Mn合金作为实验材料,加入纯氮,用差热分析和微分热分析法研究了氮对灰铸铁平衡及非平衡相变温度的影响。
