← HistoryWhich risk increases when bronze casting molds in ancient Mesopotamia are cooled too rapidly?
A)Formation of dendrites and segregation✓
B)Increased gas porosity within the metal
C)Increased hardness due to rapid quenching
D)Uniform fine-grained microstructure
💡 Explanation
When bronze casting molds are cooled rapidly, non-equilibrium solidification occurs because rapid heat extraction promotes dendritic growth and solute segregation. Therefore dendrites and segregation results, rather than porosity, hardening, or fine grain microstructure, which involve slower cooling or different alloying processes.
