Abstract

The use of rapid solidification processes such as direct strip casting (DSC) is a good way to refine the Fe-intermetallics and decrease their detrimental effects. DSC creates out-ofequilibrium supersaturated microstructures. In this work, we explore the precipitation phenomena in direct strip cast Al-Fe and Al-Cu-Fe alloys and related corrosion and mechanical properties. The precipitates are characterised with differential scanning calorimetry and transmission electron microscopy. The corrosion performances are evaluated with immersion tests and weight loss measurements and the yield strength and ductility are estimated with tensile tests. A strong correlation between the microstructure and the bulk properties is revealed with a significant improvement of properties of DSC alloys.
