Abstract
The fatigue crack growth rate (FCGR), as the standard material characteristic, is determined in air under the laboratory conditions, as for the natural conditions the fatigue crack is propogated under the effect of the ambient corrosion medium which leads to decreasing the material endurance and cyclic safety factors. The effect of corrosion medium on FCGR of Al alloys, including Al–Li alloys have been also studied.
