of cold stamping. In the hot stamping process, aluminum alloy blank is heated to solution temperature for a period of time firstly and then quickly moved to the cold die for forming and quenching... researchers found that forming temperature showed significant influence on the amount of springback. For example, LI et al [25] simulated the springback behavior of AA6061 U-shape parts under hot......
