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

A)Micro-crack lattice framework instability forms
B)Dendritic growth causes alloying segregation
C)Annealing enables rapid thermal decomposition
D)Eutectic transformation initiates void destabilization

💡 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.
