Work hardening of a material ________________?
Correct answer: B. Decreases its ductility
- A. Decreases its tensile strength
- B. Decreases its ductility
- C. Increases its ductility
- D. Does not affect its ductility
Explanation
Plastic deformation during work hardening increases dislocation density, making further deformation more difficult and raising tensile strength. The same restriction on plastic flow reduces ductility.
