Which outcome occurs when a crystal's dislocation density passes a threshold?

💡 Explanation

Increased dislocation density causes significant yield owing to dislocation pile-up, therefore yield strength decreases drastically, because plastic deformation concentrates at those locations; therefore yield occurs rather than strengthening or improved material properties; high temperatures produce different mechanisms.
