← HistoryWhen cooling bronze tools from forging temperatures in ancient Sumer, which outcome results if quenching is performed insufficiently?
A)Increased vulnerability to stress corrosion✓
B)Reduced yield strength for cold-working
C)Formation of equiaxed grain microstructure
D)Elevated concentration of alpha-phase grains
💡 Explanation
Insufficient quenching after forging bronze leads to slow cooling and segregation of elements. This causes increased vulnerability to stress corrosion because galvanic corrosion accelerates along grain boundaries; therefore, cracking appears sooner than with rapid quenching, rather than work hardening.
