In the present work macrosegregation during solidification of a 2.45 ton steel ingot is simulated with pure equiaxed model, which was tested previously via modeling benchmark experiment. While columnar structure not taken into account, packed layer formed over inner walls mold at an early stage reproduces to some extent phenomena generally related zones dendrites. Furthermore, it demonstrated t...

Abstract The Cu ingot from Velem contains approximately 10 wt.% Sb, 4.5 As, 1.2 S and Ag, as well other trace elements in an amount below 0.2 percent by weight. A 2 band running virtually across the entire width of suggests that it was formed reaction molten with antimonite (Sb 3 ). Remarkably, generated cutting surface not copper-colored but had a silvery appearance which, however, can be attr...

This study focused on the effect of electro slag remelting process (ESR) on microstructure and composition of an as-cast alloy of Cu-Cr-Zr. These observations revealed that applying ESR process results in a more uniform distribution of alloying elements, however a slight aggregation of large precipitates and inclusions existed in as-cast ingot was found. Additionally, impurities like P, S and M...
