Research of metal structurally-phase condition as the parameter of processable surfaces of machines details quality

The present work it is carried out research of one of widely applied in mechanical engineering steels - steel 35ХГС at various stages of machining. The primary goal of research consist in definition of parameters of steel gradient structuresl. Structural researches were spent by 3 basic methods: the raster electronic microscopy, translucent diffraction through thin foil electronic microscopy and X-ray structural analysis.
