Screw dislocation cross slip at cross-slip plane jogs and screw dipole annihilation in FCC Cu and Ni investigated via atomistic simulations

Critical Escaig stresses on the glide plane required for the annihilation of two oppositely-signed jogged ½〈1 −1 0〉 screw dislocations separated by 14 and 44 nm on the [1 1 −1] cross-slip plane, as a function of temperature. Also, shown are the critical Escaig stress on the cross-slip plane and critical glide stress on the cross-slip plane for the jogged screw dislocation annihilation process at 5 K.108
