Background
A forging is a workpiece or a blank obtained by forging and deforming a metal blank. The mechanical properties of the metal blank can be changed by applying pressure to the metal blank to generate plastic deformation. The forging is divided into cold forging and warm forging and hot forging according to the temperature of the blank during processing. Cold forging is generally carried out at room temperature, and hot forging is carried out at a temperature higher than the recrystallization temperature of the metal blank; the heat treatment of forgings can be divided into two groups according to the purpose of the heat treatment, and the looseness of metal can be eliminated by forging. The holes improve the mechanical property of the forging.
