ANNIHILATION BETWEEN TWO SCREW DISLOCATIONS

annihil
    Two screw dislocations are gliding on two parallel planes with opposite Burgers vectors. When they are close enough, the temperature allows them to cross slip.
    A part of one dislocation glides on the cross-slip plane to reach the other dislocation and annihilates a part of it. This phenomenon is governed by the energy minimization of the system leading to a reduction of the dislocation length.
