Purpose:

Design/methodology/approach: Light microscopy (LM), electron microscopy techniques (SEM and TEM)  in combination with X-ray analysis (SEM/EDS), and X-ray diffraction (XRD) were used.

Findings: The examinations of the as-cast alloy after slow solidification at a cooling rate 2°C/min reveal that the Si,Si, Al9Mn3(FeMn)3FeSi, α-Al15microstructure consisted a wide range of intermetallics phases, namely: ß-Al5 Si.2Si, Mg3Fe12α-Al.

Research limitations/implications: To facilitate confirmation of the achieved results it is recommended to execute supplementary analysis of the aluminium alloys, 6082 series in particular Practical implications: Since the, what involves changes of alloy properties, From a practical position it is important to understand formation conditions of the intermetallics in order to control final components of the alloy microstructure. The importance of this is due to the fact that morphology, crystallography and chemical composition of the intermetallics strongly affect the properties of the alloy.

Originality/value: This work has provided essential data about almost all possible intermetallic phases precipitating in 6000 series aluminium alloys
