How do the properties of metal change when plastic deformation is performed?

Solution

Effect of plastic deformation on properties are:

strength=due to work hardening the strength of the material increases

Ductility=Ductility decreses,the material start acquiring brittle behaviour

Toughness=ability to absorb shock is reduced by50-60% in ductile brittle transition region as a result of preliminary plastic deformation

Hardness=the mateiral becomes harder as the voids are crushed and the atoms are more firmly packed
