A Review of Our Present Understanding of Macrosegregation in IngotsOur present understanding of the mechanisms responsible for macrosegregation occurring in ingots produced by electroslag remelting (ESR), vacuum arc remelting (VAR), direct chill (DC), and continuous casting is reviewed. A detailed description is given of laboratory experiments on model Sn-Pb and Al-Cu alloys. The experimental findings are compared with theoretical predictions. Data are also presented on a high-temperature Ni-27 wt % Mo alloy ESR ingot and 2000 series aluminum alloy DC ingots. Comparison is made to theoretical predictions where appropriate.
