Studying the Intermetallic Compounds in the Microstructure of the ۸۰۰۶ Aluminum Alloy Sheets and Foils

This research studies the microstructure of the ۸۰۰۶ alloys (AlFeMn), which is transformed into sheets and foils with different thicknesses during rolling. The ۸۰۰۶ alloys are mostly manufactured through a two roller casting process. The microstructure of the sheets produced by this method is fine and suitable. The chemical formula of the alloy includes ۱.۲%-۲% Fe, ۰.۳%-۱% Mn and a maximum of ۰.۳% Si. The experiments confirm the presence of iron, manganese, and silicon compounds in the ۸۰۰۶ alloy structure during casting and rolling. A scanning electron microscopy and EDS analysis were employed to examine the intermetallic compounds, and it was determined that the particles in the intermetallic compounds of AlFeMn in foils are smaller than the particles of these compounds in sheets.
