Abstract

Some experiments were conducted to investigate the formation of iron bearing intermetallics in 319 aluminum alloy at different levels of iron and manganese. Also, the influence of solution heat treatment at 515oC for various solution zing times up to 26h on the size and morphology of iron bearing compounds was determined. The results showed that in the presence of Mn, α iron bearing intermetallics are formed in Chinese script and polyhedral morphologies and so, the addition of Mn in a sufficient level neutralizes the effect of Fe in the formation of β-needle phase. The dissolution of α-Chinese script and α- polyhedral phase was seen in the alloy solution heat treated at 515oC. Also, it was confirmed that the solution zing of the alloy can change the morphology of α phase from polyhedral to Chinese script. However, the dissolution of α phase occurs by the rejection of Si atoms from α.
