Aluminum alloys are gaining more ground as first choice materials, especially in the transportation industry where a high strength to weight ratio is of premium importance. 3004 aluminum alloy is one of the most used non-heat treatable alloys which are employed in many industries (aeronautic, aerospace, blades, discs, rings, airframes…etc.), due to its attractive mechanical properties. In this work, the mechanical parameters of 3004 aluminum alloy i.e hardness coefficients (the total hardness, hardness of GNDs and hardness of SSDs) in addition to the microstructural parameters (mean crystallite size, micro strain and dislocation density) were determined from Vickers hardness measurement by using novel methods. The flow stress and stored energy were also highlighted.
