← HistoryWhich consequence occurred when early Bronze Age smiths overheated a crucible during copper alloying?
A)Increased work hardening occurred
B)Metal-gas eutectic formed✓
C)Excessive grain growth resulted
D)Dendritic structures were refined
💡 Explanation
Metal-gas eutectic formation results from overheating, because gases dissolve more readily in the liquid metal at high temperatures and precipitate upon solidification, therefore causing porosity rather than stronger mechanical properties linked to work hardening.
