Abstract
Direct-Chill (DC) casting of aluminum ingots and billets for the subsequent manufacture of wrought product forms has been the established industry standard practice for the past 80 years. The through-thickness characteristics of aluminum products are well understood and are affected by the chemical variability introduced during DC casting by the phenomenon known as macrosegregation. In the present work, an ingot of Al-Zn-Cu-Mg-Zr was cast using a novel planar solidification approach that avoids conventional DC macrosegregation and achieves a highly uniform composition through-thickness. This ingot was fabricated to 25 mm plate and its chemical, microstructural, and mechanical characteristics are compared to a DC cast and fabricated plate of similar composition, thickness, and temper.
