Detailed explanation-1: -Plastic deformation in a general sense can be defined as irreversible deformation. Different mechanisms may be responsible: dislocation motion, vacancy motion, twinning, phase transformation, or viscous flow of amorphous materials.

Detailed explanation-2: -Plastic deformation can be defined as a non-recoverable deformation which leads to a permanent ‘set’.

Detailed explanation-3: -Permanent deformation is irreversible; the deformation stays even after removal of the applied forces, while the temporary deformation is recoverable as it disappears after the removal of applied forces.
