Abstract
Magnesium and other metal alloy sheet materials are deformed at hot forming temperatures into vehicle body panels and other articles. Many such hot forming operations are improved in speed and product quality by predetermining a static recrystallization temperature of the sheet material. As the sheet material is being heated to its hot forming temperature, deformation is commenced below the static recrystallization temperature. As heating and deformation are continued, dynamic recrystallization of the workpiece occurs and deformation may proceed faster and to a greater extent.
