Background

Currently, tempering is a metal heat treatment process in which a quenched workpiece is reheated to a suitable temperature below the lower critical temperature Ac1 (the starting temperature of pearlite to austenite transformation upon heating), and is cooled in air or a water, oil medium after a period of time. Or heating the quenched alloy workpiece to a proper temperature, preserving heat for a plurality of times, and then slowly or rapidly cooling. Are generally used to reduce or eliminate internal stresses in quenched steel parts or to reduce their hardness and strength to increase their ductility or toughness. The quenched workpiece should be tempered in time, and the required mechanical properties can be obtained through the matching of quenching and tempering. Tempering is a heat treatment process in which a workpiece is hardened, then heated to a temperature below Ac1 (the starting temperature of transformation from pearlite to austenite during heating), kept for a certain period of time, and then cooled to room temperature. Tempering generally follows quenching, the purpose of which is to: (a) Residual stress generated during quenching of the workpiece is eliminated, and deformation and cracking are prevented; (b) The hardness, strength, plasticity and toughness of the workpiece are adjusted to meet the requirement of service performance; (c) stabilizing the organization and size, ensuring accuracy; (d) improving and enhancing processability. Tempering is thus the last important step in obtaining the desired properties of the workpiece. The required mechanical properties can be obtained by the combination of quenching and tempering.
