The distribution of N and morphology of graphite in gray cast iron containing N werestudicd by adopting the man-made specimens of Fe-C-Si-Mn alloys with some N added.The N adsorbed along the interfaces between graphite and matrix together with solid-solutioned in graphite is believed to be the principal cause of morpholongical variationof graphite.
