%X The saturation dislocation microstructures in a 013] orientated copper single crystal during fatigue in air and NaCl aqueous solution were observed by electron channeling contrast (ECC) technique in SEM and TEM. The results show that the saturation dislocation structure during the corrosion fatigue in the aqueous solution of 0.5 mol/L NaCl mainly consists of labyrinth and veins dislocation structures, which differs from the dislocation structures of the PSBs and veins in the air environment. The observation reveals that the influence of environment for fatigued dislocation structures is equivalent to increase the plastic shear strain amplitude to the fatigued sample when other conditions are identical.
