摘要

The influence of various heat treatment modes on the structure, mechanical and thermal properties of 51CrV4 steel was studied. The steel was quenched in two different cooling environments and then tempered at different temperatures. After all heat treatment modes, the structure of the steel was analyzed using the SEM-EDS method and the hardness of the steel was measured, and its thermal properties were determined using the xenon flash method. Based on the results of experiments, it is recommended to use quenching in an oil bath at room temperature, followed by low or medium tempering. This heat treatment regime provides an increase in thermal diffusivity and thermal conductivity coefficient with a slight decrease in the hardness of 51CrV4 steel.
