The in situ nanometer Al2O3 particles reinforced 7055 aluminum alloy have been fabricated. The average size of endogenous particles is 42.3 nm. On the condition of 1 T, 2 T and 3 T the flake composite samples were processed by pulsed impact. In the treated samples the dislocation exhibits some specific characteristic as high density and diversity. It is analyzed that the magneto-plastic effect is the main reason that lowers the nucleation energy, accelerates the movement and increases the density of dislocations, facilitates the relief of massive internal stress. The dislocation density increases with the enhancement of magnetic induced intensity and when it equals to 3 T the maximum density is acquired. The morphology of dislocation displays as aligned, tangled, annular and spiral ones. The disordered atomic layer, deflected orientation, stacking fault and deformation twinning can also be seen. It is deduced that the dissociation of high density dislocation facilities the stacking fault and the overlap of stacking fault does the deformation twinning.
