Abstract
Twin-roll cast low-alloyed aluminum alloys are commonly used as stock materials for manufacturing of thin packaging foil. Twin-roll casting produces as-cast strips several mm thick which reduces the number of required rolling steps during processing.
However, structure of the strip is inhomogeneous and requires a high temperature annealing treatment. High annealing temperatures cause changes of intermetallic particle sizes, shapes and distributions, which affects further procesing.
Aluminum alloys with different contents and ratios of alloying elements were studied using microscopic observations and integral microhardness and resistivity measurements to assess the influence of individual elements on high temperature structural changes.
