Thin foils of aluminum alloys are commonly used in automotive industry for manufacturing heat exchangers. Use of twin-roll casting instead of direct-chill casting requires modifications in the manufacturing process and use of improved materials. In the present study, the evolution in microstructure and mechanical properties during isochronal annealing of two AW3003-based alloys differing in silicon content was monitored. The silicon influenced both the microhardness and precipitation kinetics during annealing, but not the recrystallization temperature. Precipitation of cubic alpha-Al15(Mn,Fe)3Si2 phase occurred in two steps in the material with higher Si content, while mainly precipitates of Al6(Mn,Fe) phase formed in the second material in a broad temperature interval, preferentially at grain boundaries.
