Which risk increases when casting molten aluminum solidifies, limited by mold cooling rate?

💡 Explanation

Dendritic growth becomes dominant because of slower heat extraction. This solidification mechanism favors non-equilibrium growth; so therefore solute atoms segregate to interdendritic regions, rather than forming a uniform mixture which decreases final product homogeneity.
