← HistoryWhich outcome commonly occurred during early Chinese cast iron production due to incomplete processing?
A)Increased material carbon concentration
B)Formation of brittle white cast✓
C)Superior resistance against deformation
D)Greater resistance to tensile stress
💡 Explanation
Early Chinese cast iron production often lacked precise control over carbon content and cooling rates; decarburization was not always effective. This caused cementite formation, yielding brittle white cast iron through phase transformation, rather than creating more desirable ductile iron.
