The 2024-Al and AISI 1020 steel blanks with the same diameter 506mm and several kinds of thickness are performed with explosive draw forming in which the water is used as energy-transfer medium and the air in the die cavity is compressed out through the ventholes. The diameter of the forming cone is 400mm and the maximum drawing depth is 126mm with 480mm flange in diameter. The forming technological parameters for these two kinds of metal blanks are presented. The study show fully annealed heat treatment in 2024-Al can greatly improve its forming feasibility.
