Each processing step changes the microstructure and, therefore, affects the properties of the material. The final properties of aluminum plate depend not only on the chemical composition of the material but also on the microstructural evolution throughout the processing route.

 

 

A scheme of the process chain for the production of aluminum alloy sheets and their relevant material characterization steps.

 

 

Last production step (ageing): A typical Al-Mg-Si alloy strengthening as a function of the precipitation kinetics during the last ageing treatment. In this simplified version just the evolution of b” phase during ageing has been shown.
