Which consequence directly resulted from repeated annealing cycles in early Bronze Age axe production?

💡 Explanation

Repeated annealing causes increased alloy grain boundary segregation via diffusion, reducing its strength because impurities migrate to boundaries therefore weakening it rather than strengthening metal through work hardening or altering production.

• Which risk increased upon implementing torsion catapults during Roman sieges against fortified cities?
• Which consequence resulted from al-Khwarizmi's algebraic methods neglecting geometric proofs?
• Which outcome arises when siege crossbows experienced diminished torsion during Roman military campaigns?
• Which canal failure mode became increasingly prevalent as Mesopotamian settlements expanded upstream?
• Which outcome occurs when early aqueduct stonework experiences insufficient thermal expansion joints?
• Which outcome occurs when seasonal ground freezing affects a Roman aqueduct?
