Which outcome occurs when forging metal exceeds strain hardening limits?

💡 Explanation

Exceeding strain hardening during forging causes the **work hardening mechanism** to induce embrittlement, because accumulated dislocations obstruct lattice slip, therefore grain boundary fracture is favored, rather than continued plastic deformation permitted by dislocation glide.
