The following methods can be used to prepare cemented carbide with fine grains and uniform structure:
Metallurgical method: Change the organizational structure of metal materials through heat treatment processes to obtain fine-grained structures. Commonly used metallurgical methods include annealing, normalizing, quenching, etc. Annealing is a process in which metal materials are heated to a certain temperature and then slowly cooled. Through annealing, the grains inside the metal will gradually grow and form fine grain boundaries. The size of the grains can be controlled by adjusting the annealing temperature and time. . Normalizing is a process in which metal materials are heated to an appropriate temperature, maintained for a period of time and then cooled rapidly. Normalizing can refine the grains inside the metal and improve the strength and hardness of the material. Quenching is a process in which metal materials are heated to a critical temperature and then cooled rapidly. Quenching can quickly refine the grains inside the metal and form a uniform organizational structure, improving the strength and toughness of the material.
Mechanical method: Change the organizational structure of metal materials through mechanical processing to obtain a fine-grained structure. Commonly used mechanical methods include isothermal compression, rolling, stretching, etc. Isothermal compression is a process of compressing and deforming metal materials at a certain temperature. Through isothermal compression, the grains inside the material can be refined to form a fine grain structure. Rolling is a process of deforming metal materials through the pressure of rollers or rollers. Rolling can refine the grains inside the metal and improve the strength and toughness of the material. Stretching is the process of applying tensile force to a metal material in a certain direction. Through stretching, the grains inside the metal can be stretched and deformed to form a fine-grained structure.
In the actual production process, it is necessary to select a suitable preparation method according to the product application field and specific requirements.
