Large aluminum forgings require higher equipment capacity and manufacturing technology to avoid overforming load of aluminum forgings. At the same time, it is necessary to avoid the forming defects such as flow, flow and eddy current of large complex aluminum alloy forgings. Large aluminum forgings require high strength, high toughness and high corrosion fatigue resistance, and also need to consider how to improve the uniformity of the complex structure, to avoid recrystallization, resulting in intercrystalline corrosion and fracture.
Researchers usually solve this problem by means of mold optimization design and forging process optimization design. Isothermal forging technology is an effective method to solve the problems of large forgings mentioned above.
