Which crucial risk threatened Mesopotamian bronze sickle integrity after annealing?

💡 Explanation

Excessive annealing causes grain growth, weakening the bronze. Increased grain boundary embrittlement then occurs because intergranular pathways are fewer. Therefore, crack propagation is enhanced, rather than improved ductility under continuous loading conditions.
