Mössbauer analysis of nitride and carbide dissolution in austenitic high-manganese steels under conditions of friction

Mossbauer spectroscopy is used to investigate the dissolution of nitrides and carbides in a matrix during severe deformation under dry sliding friction conditions in the case of austenite chromium manganese steels FeMr22Cr18N0.8 and FeMn20(V, Mo)C0.8. Preliminary aging reduces the number of interstitial elements dissolved in the austenite upon deformation. This is a factor in increasing adhesive wear in aged samples.
