Abstract : AMg6M aluminum-base alloy sheets 2 mm thick were subjected to explosive forming using water, sand, and rubber as transmitting media in a spherical die 120 mm in diameter. To determine the effect of shock waves reflected from container walls, forming was done in a permanent container, a thick-walled cylinder, and in single-shot polyethylene or resin-impregnated glass cloth containers. By varying the weight of the explosive charge, the specimens were deformed until cracks appeared. It was found that forming with sand required an explosive charge 4.5-5.0 times larger than forming with water for a cavity of the same size. The distribution of the maximum deformation and maximum curvature and the nature and location of ruptures along the profile of the deformed blanks were appreciably different in forming with water, sand, and rubber.
