ENG: Structural and phase transformations, as well as changes in the microhardness of the matrix, austenite-carbide eutectic, and total hardness that occur in chromium–manganese alloys in the cast state during wear by friction under different loads are studied. As shown, a high wear resistance of chromium–manganese alloy (C—3.1%, Cr—13.1%, Mn—15.75%, Ni—1.15%) is associated with high microhardness of the matrix, austenitic-carbide eutectic based on Me7C3 carbide and determined by the degree of doping and the parameter of the shape of the eutectic carbide, as well as due to the deformation-phase transformations that occur in the investigated alloys during friction wear.
