Heat treatment: Quenching and tempering; normalizing and tempering; Annealing
The following are the definitions and applications of common processes in heat treatment:
Quenching and Tempering: Quenching is the rapid cooling of metal materials heated to a certain temperature from a high temperature to achieve rapid solidification and high hardness and strength. Subsequently, tempering is carried out by reheating the material to a lower temperature, followed by appropriate cooling to reduce the internal stress generated during quenching, improve the toughness and toughening treatment of the material. This process is often used to manufacture parts that need high strength and toughness, such as Machine element, automobile engine parts, etc.
Normalizing and Tempering: Normalizing is the process of cooling a metal material heated to a certain temperature in air to obtain uniform and fine microstructure and good mechanical properties. Subsequently, tempering treatment is carried out, and the material is reheated at an appropriate temperature and cooled appropriately to reduce its hardness, improve its machinability and toughness. This process is often used in the production of quenched and tempered steel or Tool steel to improve the strength and wear resistance of materials.
Annealing: Annealing is the process of heating a metal material to a certain temperature, slowly cooling it to room temperature after an appropriate holding time. Annealing aims to eliminate internal stress in materials, improve their plasticity and toughness, and reorganize and grow grains. This process is often used to reduce Hardness, improve machinability, and improve bending and tensile properties of materials.
Through different heat treatment processes, the microstructure and properties of materials can be significantly changed to meet specific usage requirements. Therefore, heat treatment processes such as quenching and tempering, normalizing and tempering, and annealing have important application value in the manufacturing and processing of metal materials.
