  • Descrição: Methods of Mossbauer spectroscopy and electron microscopy analysis of high-nitrogen chromium manganese steel FeMn 22 Cr 18 N 0.8 have been used to investigate the processes of dissolution of the products of cellular decomposition in austenite matrix upon severe deformation under the conditions of dry sliding friction and shear under pressure in Bridgman anvils. Deformation-induced redistribution of nitrogen from the chromium nitrides to interstitial positions of the quenched and preliminary aged steel has been determined. According to the data of Mossbauer analysis the depth of dissolution of chromium nitrides and the increase of content of nitrogen in steel matrix upon friction is 10 μn and more. Aging decreases the amount of nitrogen which transfers to the solid solution under deformation. This is a factor of the enhanced adhesive wear in the aged samples.
