Improving the wear resistance of steel products by using non-standard heat treatment modes. Foundryproductionandmetallurgy

Abstract

The use of non-standard modes of heat treatment increases the density of dislocations in the crystal structure of the α-phase and increases the wear resistance of carbon, low-alloy steels under various friction conditions, which is comparable to the results when heated to a standard temperature (Ac 3 + 30–50 °C). The preliminary extreme heating temperature is determined. After requenching at standard temperature and low tempering, the wear resistance of steels under various types of friction increases by up to 40 % compared to standard quenching.
