... rule) in the mushy zone. It demonstrates that such a model is able to predict stratification in the solute from the liquid phase and mushy zone during the solidification. The effect of the sedimentation on macrosegregations and channel segregation or freckles which develop during the solidification...

... EM stirring and ( b ) with intermittent electromagnetic stirring. Freckles are visible in the right part of the samples. Experimental conditions are: DT = 40 K, CR = 0.03 K/s. X-rays of the solidified ingots showing the lead segregations (in white) for Sn–10 wt % Pb alloy. (a) Without any EM...
