Исследование формирования деформационного рельефа на поверхности карбидосталей - карбид вольфрама - железомарганцевая сталь

Abstract

The evolution of the deformation relief on the surface of samples of cemented steels WC - (Fe-Mn-C) during axial compression tests was studied. It was found that in the process of deformation of carbide steels on the polished end surface, an ordered deformation macro-relief in the form of bands of localized deformation is formed. The bands are oriented in two directions and propagate independently of the material structure. With an increase in the average distance between the bands, the compressive strength and ultimate deformation before fracture decrease. It is shown that the values of the fractal dimension of the profile of the deformed surface increase with increasing deformation and depend on the average distance between the bands of localized deformation.
