Atomistic structure of the edge (90°) and mixed (130.893°) dislocation in FCC Al. (a) compact core structures after imposing the Volterra field/before the relaxation. (b) core structures after relaxations. The atoms are colored by coordinates of the y axis. Black, dark gray, gray, and white atoms are placed on top, 2nd, 3rd and 4th layers in the y axis from the slip plane. The initial compact dislocation lines dissociate into two Shockley partial dislocation lines indicated by the black arrows
