Effect of friction deformation on the structure and properties of a metastable austenitic chromium-nickel steel

Abstract

The effect of surface friction deformation on the phase composition, structure, and strength properties of a ribbon produced from a chromium-nickel steel with metastable austenite is studied. It is shown that friction processing intensifies the γ-α transformation, creating favorable conditions for the formation of a highly dispersed structure in a thin surface layer and, thus, increasing the microhardness, the elastic limit, the fatigue stability, and the Bauschinger effect. © 2013 Pleiades Publishing, Ltd.
