Abstract This article compares the flow stresses of commonly forged aluminum alloys with those of 1025 carbon steel forged at typical forging temperatures and various levels of strain. It describes various forging methods, such as open-die (or hand) forging, closed-die forging, upsetting, roll forging, orbital (rotary) forging, spin forging, mandrel forging, ring rolling, and extrusion. The article also discusses forging equipment and processing steps in the manufacture of aluminum alloy forgings.
