← HistoryWhich increased risk occurred for bronze cannons when early founders exceeded the prescribed pour rate?
A)Increased alloy segregation weakens structure✓
B)Elevated hydrogen inclusions induce embrittlement
C)Increased mold cracking causes dimensional errors
D)Reduced cooling rate affects grain size
💡 Explanation
Faster pouring increased alloy material FEEDING which, because the bronze solidifies more rapidly than compositional balancing can occur, created a composition gradient called alloy segregation, therefore weakening the cast structure, rather than the formation of hydrogen inclusions.
