Abstract

The gradient structure formed in the surface layers of Hadfield steel under dry sliding friction was studied using Mössbauer spectroscopy and electron microscopy. Structural-phase transitions are established in the contact stress zone on the steel surface. The 20-μm-thick surface layers reveal deformation-induced short-range ordering with an increased number of neighboring manganese and carbon atoms. Thinner (up to 1 μm) layers are composed of nanocrystalline carbides of the (Fe,Mn)3C type.
