← HistoryWhich outcome can develop if tin-bronze implements are repeatedly cold-worked?
A)Increased alloy malleability develops
B)Work hardening induces brittleness✓
C)Eutectic grain boundary strengthening
D)Recrystallization elevates yield strength
💡 Explanation
Work hardening leads to dislocations accumulating within the bronze's crystalline structure because continued plastic deformation introduces more defects. Therefore, its ductility decreases, facilitating brittle fracture, rather than increased malleability achieved through annealing.
