Strain hardening decreases ductility, therefore B is the correct answer.

Tarik said:   5 years ago
Generally, Strain hardening will decrease ductility.

Anup said:   8 years ago
But as ares of cross section is decresed i.e. material is strain hardened so it will also affect ductility so I think it will decrease.

Ductility is proportional to percentage reduction in area.

Malleability is the property which permits the material to extend in all directions (like sheets) and not in only one direction (like wire).

Deepesh said:   8 years ago
Malleability is the property by which material can be drawn into wires not ductility.

It should remain same though as it is a material property.

Ductility is property by which material can be drawn into wires. As area is reducing means it is forming a shape like wires i.e. ductility has increased.

Ram said:   1 decade ago
Ductility is property of material, it can not be change.
