Numerical predicting of recycling friendly wrought aluminium alloy compositions

Keywords: Aluminum alloy, recycling, numerical predicting.


The model presented in this work enables the design of optimal (standard and non-standard “recycling-friendly”) compositions and properties of wrought aluminium alloys with significantly increased amounts of post-consumed scrap. The following two routes were modelled in detail: (i) the blending of standard and non-standard compositions of wrought aluminium alloys starting from post-consumed aluminium scrap sorted to various degrees simulated by the model; and (ii) changing the initial standard composition of wrought aluminium alloys to non-standard “recycling friendly” ones - with broader concentration tolerance limits of alloying elements, without influencing the selected alloy properties, specified in advance.
