INTERACTION BETWEEN TWO SCREW DISLOCATIONS WITH OPPOSITE BURGERS VECTORS

screw
Two screw dislocations moves on parallel glide plans with opposite Burgers vectors. The distance between the glide plane is chosen so that the cross-slip is difficult.

When the dislocation arms are close enough, they slow down because of the intercation stress fields.

Then, they continue on their way
