introduction：Forgings for obtaining good organizational properties，In addition to the need to ensure good raw material quality，Also need to have a reasonable forging process and heat treatment process。 The forging process is generally composed of the following processes，Immediate blanking、heat、shaping、Post-forging cooling、pickling（corrosion）And heat treatment after forging。The forming process includes free forging、Die forging、Trimming and calibration；Free forging includes upsetting、Drawing out、punching、Bending and twisting, etc；Die forging includes drawing、roll-extruding、preforge、Final forging and heading, etc。 From the above process，The influence of forging process on the structure and properties of forgings，Ultimately, it comes down to thermodynamic factors。
