Question
History

Which phenomenon limited the size of castings when early metallurgists poured molten bronze for large statues?

A)Undercooling prohibits complete metal solidification
B)Segregation causes compositional non-uniformity
C)Hot tearing induces cracking upon cooling
D)Dendritic growth hinders directional solidification

💡 Explanation

Hot tearing posed a limit because tensile stresses developed during non-uniform cooling exceeded the cohesion of the solidifying bronze microstructure; therefore, the metal cracked, rather than maintaining structural integrity with larger statue dimensions.
