Which outcome follows when casting low-carbon steel ingots without subsequent homogenization?

A)Macrosegregation leads to composition variations
B)Higher ductility throughout the entire volume
C)Significant grain refinement is observed
D)Reduced risk of centerline porosity defects

💡 Explanation

Macrosegregation arises during solidification due to varying solubilities, therefore composition varies spatially rather than uniform material; because elements redistribute during phase changes, rather than diffusing readily especially at lower temperatures below any substantial homogenization step.
