Jet processing of direct chill cast aluminum ingots
Macrosegregation of solute elements during casting operations has been a subject of observation, discussion, and research for several hundred years. The unique casting conditions found in the Direct-Chill aluminum casting process can lead to significant accumulation and depletion of solute elements …

A rotating disk study of impurity segregation in aluminum alloy solidification
… increase the amount of recycled scrap in direct-chill cast aluminum ingots, they face rising levels of impurities that threaten the quality of the aluminum alloys produced. The harmful effects of impurities are exacerbated by convection-induced macrosegregation of impurities within ingots, which …

Microstructural evolution during the homogenization heat treatment of 6XXX and 7XXX aluminum alloys
<p>Homogenization heat treatment of as-cast billets is an important step in the processing of aluminum extrusions. Microstructural evolution during homogenization involves elimination of the eutectic morphology by spheroidisation of the interdendritic phases, minimization of the microsegregation …

Characterization of novel microstructures in Al-Fe-V-Si and Al-Fe-V-Si-Y alloys processed at intermediate cooling rates
… Y additions were prepared by copper wedge-mold casting. Analysis of the microstructures developed at intermediate cooling rates revealed the formation of an atypical morphology of the cubic α-Al12(Fe/V)3Si phase (Im3¯ space group with a = 1.26 nm) in the form of a microeutectic with α-Al that …
