| The Microstructure and tensile properties of 60 µm thick AA8006 aluminum foil were investigated in the present study. Sheets of AA8006 were produced by twin-roll casting (TRC) with a thickness of 8 mm and were reduced to 4.5 mm thickness by one pass of rolling. The sheets were heat-treated, homogenized and annealed. After heat treatment, both processes were subjected to cold rolling to compare their tensile properties in 60 µm thickness after final annealing at different temperatures. The results showed that after homogenization, the short rod like eutectic phase is dispersed homogeneously in Al matrix of homogenized TRC processed alloy. The EDS results show that the contents of iron and manganese elements in the eutectic phase of TRC processed alloys decrease after homogenization, with the difference that this decrease is more noticeable in the thickness of 4.5 mm after annealing. It was also found that the homogenized sheet with a thickness of 60 micrometers after a rolling step was compared to the homogenized sheet after casting, due to smaller spherical intermetallic particles and better grain structure after heat treatment, the relative elongation from 12% to 27.5% showed an increase. | ||
