| Abstract Scope |
Strontium (Sr) is commonly used as a modifier in casting to refine silicon- and iron-based intermetallics, improving microstructure in conventional aluminum alloys. However, its effect in twin roll casting (TRC)—especially for thin-gauge aluminum foil products—has not been thoroughly investigated. In foil-grade 8011 alloys, where microstructural uniformity and mechanical consistency are crucial, the influence of Sr remains unclear.
This study explores the effect of Sr additions (0, 30, and 90 ppm) via AlSr10 master alloy on the microstructure and mechanical properties of TRC-processed 8011 aluminum. After homogenization, the materials were cold rolled at different deformation ratios to final foil thickness. Intermetallic morphology, particle distribution, and homogenization rates were examined. Additionally, pinhole density was measured at final gauge. The findings offer new insight into how Sr affects the internal structure and tensile properties of aluminum foils produced via TRC. |
