Aluminum Monolithic Alloy and Multi‐Alloy Cast Using Planar Solidification Approach

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 phenomena of macrosegregation which occurs during casting. In the present work, two new classes of alloy ingot were cast using a novel planar solidification approach. One class is a monolithic alloy ingot with a highly uniform composition through the thickness. The other class is multi-alloy ingot with engineered compositional gradients through the thickness. The chemical and microstructural characteristics of these cast materials are discussed and compared to conventional DC ingot.
