← HistoryWhich outcome results when Bronze Age smelting furnaces cooled too quickly?
A)Reduced alloy strength resulted✓
B)Increased carbon content occurred
C)Recrystallization initiates rapidly
D)Metal oxide formation accelerates
💡 Explanation
Ductility reduces because rapid cooling during casting introduces thermal stress Concentration, creating internal cracks and defects. This embrittlement decreases alloy strength rather than improving microstructure. Therefore, annealing was implemented to moderate cooling; rather than allow uncontrolled solidification.
