The objective of present paper is to investigate the warm deep-drawing process of laminated sheets consists of aluminum alloy series 1050, 5052 and stainless steel 304(SUS) experimentally. The effects of temperature within the blank on formability and punch force are investigated. To study the laminate sheet behavior; three blank temperatures namely, 25̊ C, 100̊ C and 160̊ C are examined. In addition, the effect of grain size on punch force and material behavior for aluminum alloys 5052 and 1050 are studied. The aluminum sheets are annealed at 350̊ C 400̊ C and 450̊ C. The grain size effect, which strongly affects some properties such as formability parameters, stress, elongation and friction coefficient, is investigated. To measure the grain size the microstructure of Al 5052 and Al 1050 sheets is revealed by Polarized Light Microscope (PLM). In addition, to clarify the relative influences of grain size on the formability of Al 5052, some tensile tests on annealed specimen at 350̊ C, and 450̊ C are performed. It is found that the effect of grain size and sheet temperature on punch force may be dissimilar for different blank-holder forces.
