Which microstructural outcome decreased bronze tool durability during annealing?

💡 Explanation

Preferential grain boundary oxidation reduced durability because oxidation weakens the boundaries, therefore causing intergranular fracture rather than increased bulk strength, which dislocation entanglement annealing otherwise leads into bulk strength
