In the siege of Alesia, which outcome occurred if the Roman legionaries improperly tempered gladius blades?

💡 Explanation

Improper tempering leads to excessive brittleness, so a brittle blade is exposed to stresses beyond its fracture toughness during combat at Alesia. This initiates catastrophic crack PROPAGATION because of reduced ductility and therefore makes blade shatter, rather than bend elastically or corrode.
