← HistoryWhich effect most limited maximum quenching rate in Mesopotamian bronze metallurgy?
A)Oxide layer formation impeding cooling
B)Dissolved gas precipitating within grains
C)Slow heat extraction due to material✓
D)Eutectic phase formation at grain boundaries
💡 Explanation
During quenching, slower heat extraction because of bronze's thermal conductivity limited the rate, delaying martensite formation which necessitated less reactive, less powerful quenching mediums like oil. Therefore slow heat extraction dominates rather than oxidation, outgassing, or eutectic formation requiring distinct alloy conditions or quench media.
