Which outcome resulted from preferential arsenic segregation in early Bronze Age arsenical bronze axes during casting?

💡 Explanation

When arsenical bronze cools non-uniformly, arsenic segregates to grain boundaries, weakening cohesion because it embrittles the metal locally, increasing crack propagation. Therefore, brittle fracture risk results, rather than enhanced edge-retention, corrosion resistance, or reduced density, which demand uniform dispersion of arsenic or different mechanisms.
