FEATURES OF CHOOSING TEMPERATURE REGIMES FOR CHROMIUM-MOLYBDENUM STEEL FOR SUBSEQUENT HEAT TREATMENT
Abstract
Research on the heat treatment of various alloys requires the selection of more favorable thermal regimes, as the choice significantly affects the thermomechanical properties of the alloys. We present the development of a technology to improve the strength and wear resistance characteristics of chromium-molybdenum steels through the optimization of heat treatment regimes. Experimental studies confirmed that short-term intensive heating followed by rapid cooling leads to a significant improvement in the operational properties of the alloys. These processes result in increased hardness, wear resistance, and fatigue strength, which is particularly important for components working under high loads and abrasive wear conditions.
