Which microstructure outcome resulted from quenching irregularities during early bronze tool production?

💡 Explanation

When a bronze tool is quenched unevenly, differential cooling rates result because varying thicknesses cool at different speeds, leading to internal stress concentrations. Therefore, brittle fracture risk increases, rather than improved strength, reduced corrosion, or ductility, which need controlled temperature treatments.
