Increased crossbow performance during China's Han Dynasty resulted when increased quenching rates induced which material property change?

💡 Explanation

Faster quenching increased carbon diffusion, driving martensite formation. Martensite causes work hardening, which increases yield strength because the steel withstands higher elastic deformation before permanent changes occur; therefore, allowing greater force storage compared with options A/B/D.
