摘要: 本文用波谱和俄歇能谱测定了Fe-C-Si-Mn灰铸铁凝固过程中氮的分布,并用x射线衍射仪测定了加氮前后灰铸铁中铁素体和渗碳体晶格尺寸的变化,以揭示在灰铸铁凝固后的固态相变中氮的分布。本文的研究工作为解释氮在灰铸铁中的作用机理提供了实验依据。

Abstract: The distribution of nitrogen during solidification process of Fe-C-Si-Ma gray cast iron was revealed by using WDX and AES. The existence of nitrogen in ferrite and cemenlite was studied by measuring the change of the crystal lattice size with x-ray diffraction procedure.
