Redistribution of Second Phase Particles in Surface Layers of Deformed Roll

Abstract:

Using optical and electron microscopy and also X-ray diffraction laws were investigated of carbide phases particles redistribution in the roll near-surface layers (at surface and at distance of 0.5 mm, 2 mm from surface) made of 30CrMnSiА steel during hot deformation. There are located at borders and joints of isotropic and anisotropic fragments and also inside these fragments. Shows the dependence of carbide phases volume fraction (cementite and special carbides). There are located in different structural components and different locations of the roll surface layer. Shows a relationship carbides with dislocation substructure. Shows a gradient character in the laws of carbide phases distribution as they approach the roll surface.
