Aluminum alloy AA5754 is used for many technical and industrial applications. Twin roll casting is unique among the casting processes in that it is a combined "solidification/deformation" technique. The simultaneous solidification and hot rolling produces characteristic microstructure with a fine cell size and intermetallic particle distribution with some residual structure. In the study, first AA5754 alloy (tread and plain sheet) strips were fabricated by using a twin-roll caster equipped with water-cooled steel-rolls. To reduce the thickness of the strip, cold rolling process was applied until strip thickness got 3 mm. After homogenization step the strips were cut in to smaller specimens and annealed at 260°C, 285°C, 310°C, 340°C, 370°C, 400°C, 430°C, 460°C, 490°C, 520°C for 3 hours to obtain the desired temper conditions. Mechanical properties were investigated after processes. Tensile, hardness and bending tests were applied to monitor the effect of annealing after cold rolling process.
