Common plastic deformation modes of metal materials

The common plastic deformation mode of metal materials is sliding. The forms of plastic deformation are slip and twin, and slip is a common plastic deformation mode. Slip refers to the phenomenon that one part of a crystal slides along a certain crystal plane and crystal direction relative to another part. Twin refers to a common plastic deformation mode, in which one part of a crystal is sheared relative to another part along the crystal plane and the twisting direction.
