History

Which 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.
