a 1 0 0 Dislocations are observed in nickel-base superalloys after creep deformation at high temperatures and low stresses. They are formed in the β₯/β₯ interfaces by a three step mechanism. First, primary dislocations with Burgers vector a/2 1 0 1 and 60 β€’ character are left behind in the interfaces
