Abstract
Steel 20KhN2M is used for the production of gears and other components, for whose service enhanced wear resistance is required in retaining resistance to impact loadings. The deformation (warping) and increased brittleness of these components are observed after their bulk hardening. The deformation of the components cannot be completely eliminated, even on hardening with the use of superhigh frequency, radiation. Local laser heating lowers deformation to a significant degree. In this connection. it was interesting to study the effect of laser radiation on the mechanical properties of the indicated components.
