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 solidi cation/deformation technique. The simultaneous solidi cation and hot rolling produces characteristic microstructure with a ne cell size and intermetallic particle distribution with some residual structure. In the study, rst 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 e ect of annealing after cold rolling process.
