Which outcome resulted from tempering challenges in crucible steel production, particularly in antiquity's Damascus?

💡 Explanation

Improved blade resilience occurred due to heterogeneous carbon nanoparticle distributions achieved by the Bloomery process; this fostered work hardening. The mechanism exploits work hardening rather than simpler precipitation hardening, therefore toughness improvement results rather than other material properties.
