... working methods include extrusion, forging, rolling, and drawing. Some methods, such as open-die forging and radial forging, are used in both primary mill production and in the production of finished parts. In contrast to bulk forming, sheet forming typically involves local deformations. During sheet...

The first step in deforming as-cast ingots is a series of slow-speed steps including upset forging, side pressing, and press cogging to help homogenize the structure and break up the transformed beta structure. Cogging is a simple open-die forging process between flat dies conducted in slow-speed...
