Which mechanical consequence results when arsenic content varies significantly within a cast bronze Adze blade?

💡 Explanation

When arsenic content varies significantly within bronze, microstructural heterogeneities occur altering the alloy’s mechanical properties, leading specifically to increased susceptibility to brittle fracture under tensile stress. Therefore, brittle fractures in the bronze result, rather than grain growth, wear resistance or friction reduction, all requiring different uniform compositional parameters and processing steps.
