Which metallurgical limitation causes bronze tools to deform under repeated heavy hammering compared to steel?

💡 Explanation

When bronze undergoes repeated hammering, grain boundary sliding occurs because the relatively large grain size and lack of strong covalent bonding allow gradual plastic deformation at grain interfaces, leading to decreased yield strength. Therefore grain boundary sliding leads to greater deformation, rather than increased strain, cracking, or corrosion, which require different material characteristics and failure mechanisms.
