Resumo
This study quantitatively evaluates the variation in the distribution, density, size, and chemical composition of constituent intermetallic particles (IMPs) in different commercial high strength aluminium alloys, including Al-Cu-Mg (AA2024-T3), Al-Cu-Li (AA2198-T8/T851), and Al-Mg-Zn (AA7475-T761) alloys. It is observed that the AA2024-T3 alloy is characterized by three primary types of IMPs (Al-Cu-Mg, Al-Cu-Fe-Mn, and Al-Cu-Fe-Mn-Si) and the highest particle population density. In contrast, the Al-Cu-Li alloys contain a single type of IMP (Al-Cu-Fe), while the AA7475-T761 alloy exhibits the lowest population density of IMPs that are distinguished by varying copper contents.
