[0002] Forging is a processing method that uses forging machinery to apply pressure to a metal blank, causing it to undergo plastic deformation to obtain forgings with certain mechanical properties, shapes, and dimensions. It is one of the important processes in metal processing and belongs to the category of pressure processing; the core points of forging: the basic principle of forging - plastic deformation: by applying external force, the metal undergoes deformation above or below the recrystallization temperature, changing its shape without destroying its integrity. Improving properties: Forging can refine the metal grains, densify the organizational structure, and improve strength, toughness, and fatigue life (compared with castings).
