Dislocation density is increased and the dislocation is strongly tangled. The level of the increasment and the tangled stability become less as the intensity of shock wave deteriorates.Most dislocations are generated in and close to the grain boundaries.Dislocation structure and morphology in different plane are different, dislocation density and tangle stability in plane {110} is the strongest.And dislocation density and morphology in ferrite investigated do not correspond to dimention of ferrite grain.
