Micro addition on HPDC Aluminium alloys: effect on microstructure and properties

The degree thesis aims to analyze the effect of the most significant chemical species present in secondary aluminum alloys, such as iron, silicon, manganese, magnesium, copper, and titanium, when these are presently more than the established limits by international standards, evaluating their effects on their mechanical properties and microstructure. Thus, the results serve to understand how secondary aluminum alloys, or recycled aluminum, would perform in reality, where there are often significant concentrations of impurities or chemical elements present beyond a tolerance threshold. These alloys were created in the laboratory through controlled micro additions so that each chemical composition could be likely to that of alloys deriving from recycled aluminum.
