Influence of Isothermal Quenching Modes on the Wear Resistance of High-Strength Cast Iron

Abstract—The possibility of increasing the wear resistance of ductile VCh500-7 iron by isothermal quenching using a new method is studied. It differs in that cooling and holding are carried out according to the water–furnace scheme, not in a molten salt and alkali, as in the current technology. An increased level of wear resistance is achieved by obtaining in the structure, along with lower bainite and graphite, 20–37% metastable residual austenite. The isothermal quenching according to the new method is environmentally friendly and more economical than that currently used.
