Aluminum Science and Technology
This article reviews the critical elements of the aluminum forging process, such as workpiece and die temperatures, strain rate, deformation mode, and type of forging process, including state-of-the-art forging process capabilities and design aspects of forged parts. It schematically illustrates the relative forgeability of ten aluminum alloys that constitute the majority of aluminum alloy forging production. The article explains the various types of forgings, including open-die, closed-die, upset, roll, orbital, spin, and mandrel forging. It describes forging equipment, including hammers, mechanical and screw presses, and hydraulic presses. The article concludes with a discussion on postforge processing in terms of trimming, forming, repairing, cleaning, and heat treatment.
