During early Chinese cast iron production, which inherent casting risk reduces overall cannon barrel integrity?

💡 Explanation

Dendritic microsegregation causes compositional inconsistencies in the solidified cast iron, weakening the material because segregates form planes of weakness. Therefore, the cannon is prone to breech failure rather than consistent wear, due to inhomogeneous microstructure.
