Abstract

Abstract This study explores the effect of aging on the structure and characteristics of the metal of composition G7M3S2AFTYu deposited by flux-cored wire. The best results were obtained at a temperature of 550 °C, maintained for 6 h. It was shown that hardening of steel as a result of aging is due to the release of particles of the intermetallic compounds Fe0.875Mo0.125, Fe0.91Si0.09, V1.98Ti0.02, carbonitride Ti2CN, nitride MnN0.457 and VC carbide. As a result of the experiment, we obtained high values of the metal hardness after aging. Therefore, we recommend this steel for surfacing parts operating under conditions of moderate wear.
