Which outcome increased the effectiveness of early Mesopotamian bronze armor fabrication?

💡 Explanation

Alloying copper with tin induced grain boundary strengthening, where dislocations are impeded, boosting bronze hardness and protection, because these smaller grains enhanced blocking, therefore reducing fracture spread, rather than larger grain sizes weakening the overall material.
