In ancient bronze metallurgy performed during casting, which outcome arises from oxygen contamination within the molten alloy?

💡 Explanation

Oxygen contamination promotes segregation via oxidation during solidification, forming oxide inclusions and discontinuities. This defect acts as stress concentrators that greatly increase the risk of brittle fracture because grain boundary cohesion significantly reduces, therefore lessening resilience, rather than increasing ductility.
