Partial softening heat treatment of aluminum alloy sheets was investigated using heat transfer between the sheet and a couple of heated metal dies to prepare a peripherally softening blank for deep drawing. It was found, from the heat conduction analysis, that the aluminum blank could be heated to the temperature of the heated dies by contacting with them in less than 1 s and the temperature gradient more than 20 degrees/mm could be obtained near the contacting region. The temperature of the sheet contacted with the heated dies depends on heat transfer from the heated dies and the temperature recovery of their surfaces. Production of the peripherally softening blanks was examined for 5052-H24, 1100-H24 and 6061-T6 aluminum alloy sheets. In the blank of 6061 aluminum alloy sheets, the difference in hardness of the central hard part and the peripheral soft part was about 1.8 times. The softening region was changeable according to inner diameters of the heated dies.
