Purpose: The main objective of this study was to analyze the morphology and composition of complex microstructure of the intermetallic phases in AlSi1Mg alloy. Design/methodology/approach: In this study, several methods were used such as: optical light microscopy (LM), transmission (TEM) and scanning (SEM) electron microscopy in combination with X-ray analysis (EDS) using polished sample, and X-ray diffraction (XRD) to identify intermetallics in AlSi1MgMn aluminium alloy. Findings: The results show that the as-cast microstructure of AlSi1MgMn alloy after slow solidification at a cooling rate 2 degrees centigrade/min, consisted a wide range of intermetallics phases. By using various instruments (LM, SEM, XRD) and techniques (imagine, EDS) the: alpha-A15FeSi, alpha-Al15(FeMn)3Si, A19Mn3Si, alpha-Al12Fe3Si, Mg2Si intermetallic phases were identified. Research limitations/implications: In order to complete and confirm obtained results it is recommended to perform further analysis of the 6000 series aluminium alloys. Therefore it is planned to include in a next study, microstructure analysis of the alloy by using transmission electron microscopy technique (TEM). Practical implications: Since the morphology, crystalography and chemical composition affect the intermetallic properties, what involves changes of alloy properties, from a practical point of view it is important to understand their formation conditions in order to control final constituents of the alloy microstructure. This paper has provided essential data about various intermetallic phases precipitating in 6000 series aluminium alloys. Originality/value: This paper proposes the best experimental techniques for analysis of the intermetallic phases occuring in the 6xxx series aluminium alloys, provide wide description of the intermetallics formation through all possible reactions and data about their chemical composition, morphology and crystallography.
