| dc.description.abstract | Metalworking processes are commonly classified as either hot working or cold working operations. Primary metalworking processes, such as the bulk deformation processes used to conduct the initial breakdown of cast ingots, are always conducted hot. The term bulk deformation implies large amounts of material movement, such as in hot rolling or forging. Secondary processes, which are used to produce the final product shape, are also conducted either hot or cold. Some secondary processes, such as sheet forming, do not involve large amounts of deformation. Two 6061 occurrences in a table. | en_US |
