摘要：

A number of intermetallic compounds can potentially form in the A3003 series of aluminium alloys, such as Al3Fe, Al6Mn, Al2Cu and alpha-Al15Si2M4, as well as Al9Fe2Si2 and Al8Fe2Si, despite of the low alloying element contents. The phase formation depends on not only the metallurgical history but also the actual alloy composition, as illustrated with Calphad calculations. Considering a specific alloy composition, the phase formation during solidification and consequent heat treatment was discussed. It has been demonstrated that the deviation from equilibrium conditions and the impact of composition segregation can be interpreted with a combination of different types of calculations.
