Modern understanding of possible mechanisms of crack growth in corrosion cracking of aluminium alloys immersed in various corrosion media such as aqueous solutions, saturated and undersaturated vapour, gaseous hydrogen, etc. is discussed in this review. The experimental data used as a basis to conclusions about the mechanisms of corrosion cracking in aluminium alloys are critically examined. A special emphasis is given to new methods to determining the effect of local anodic dissolution and hydrogen embrittlement in crack growth, i.e. the method of comparative tension and torsion tests deformations of types I and III, and the method based on evaluating ambiguous effect of cathodic polarization on crack growth.
