← HistoryWhich consequence arises when rapidly pouring molten cast iron in the ancient Chinese process?
A)Increased carbon monoxide degassing rate
B)Faster graphite nodule precipitation occurs
C)Increased risk of dendrite formation✓
D)Reduced silicon dissolution into solution
💡 Explanation
Dendrite formation increases because greater differences in the temperatures of the molten material and the mold's surface means faster solidification rates; therefore, less time is spent in equilibrium micro-constituent propagation rather than normal crystal growth.
