- The formation of interdendritic crack of continuously cast aluminum alloy slabs has been studied by macrosegegation analysis of cast samples and by performing a set of mathematical analyses of heat flow, solidification, interdendritic strain and interdendritic cracking criteria. The study has revealed that the interdendritic cracking phenomena depends mainly on the interdendritic coherernt region width and the accumulated interdendritic strain generated due to various cooling conditions during dendritic solidification process. Interdendritic crack is expected in the positive segregation areas where the tensile strain is present. The morphology of this crack depends mainly on the kind, degree and pattern of macrosegregation.
