In the first stage of polishing, it was observed that comparatively sharp reflections of Fe were overlapped with several reflections of oxides a little diffused. In the 2nd stage the diffusion of diffraction rings advanced and the discrimination of individual lines became difficult except the (111) of Fe₃O₄. But the position of general maximum of the intensity suggested further formation of oxides. This inclination proceded for some time. In the final stage of polishing the diffraction patterns became very akind to those so-called the general halo-patterns of polish, although the diffused (111) line of Fe₃O₄ never distinguished. According to the results of the experiments it was interpreted that the progression of oxidation was great in the beginning stage of polishing, while in the final stage the oxidation became weak or stopped. The displacement of the general maximum of halo-rings in the final stage might even be thought to suggest the reformation of Fe or the reduction. The resulted halo-patterns of polished Fe were interpreted to be the complicated duplication of diffused lines of Fe and Fe₃O₄ and the essential halo-rings by the polished structure of Fe. The surface structure of polished Fe was such that the Fe matrix was finely inlayed and all over by strongly deformed fine particles of oxides, as verified by the persistent survival of (111) line of Fe₃O₄.
