The effect of friction impact on structure and properties of mangalloy (Hadfield steel) was investigated. By means of metallographic analysis coupled with synchrotron X-ray diffraction in operando regime, the microstructural changes in specimen' subsurface layer during pin-on-disk experiment were studied. Analysis of phase composition showed that formation of martensite side by side with austenite has a cyclic behavior. Besides, it was shown that overall hardening is associated with a set of
