Which risk was amplified in Mesopotamian bronze axe-heads due to repeated low-temperature use?

💡 Explanation

With repeated low-temperature use followed by impact stress cycles, the bronze in axe-heads could undergo recrystallization because of the gradual rearrangement of the atomic lattice, resulting in localized annealing and softening, thus leading to loss of temper. Therefore loss of temper results, rather than increased hardness, reduced ductility, or accelerated corrosion, which require different metallurgical processes.
