← HistoryWhich outcome follows if early bronze tools experience work hardening?
A)Reduced ductility and fracture✓
B)Increased resistance to corrosion
C)Enhanced thermal conductivity quickly
D)Improved electrical conductivity overall
💡 Explanation
Work hardening increases hardness but decreases ductility because strain accumulation creates dislocations, therefore the metal becomes brittle and prone to fracture, rather than gaining better corrosion/thermal or electrical properties, which arise from different mechanisms.
