This article examines aluminum forging processes, including open-die, closed-die, upset, roll, orbital, spin, and mandrel forging, and compares and contrasts their capabilities and the associated design requirements for forged parts. It discusses the effect of key process variables such as workpiece and die temperature, strain rate, and deformation mode. The article describes the relative forgeability of the ten most widely used aluminum alloys, and reviews common forging equipment, including hammers, mechanical and screw presses, and hydraulic presses. It also discusses postforge operations such as trimming, forming, repairing, cleaning, and heat treatment.
