Abstract
In the present paper, the fatigue crack growth retardation following a single tensile overload applied to the 8090 alloy is studied and compared with results obtained from conventional aluminium alloys. The 8090 alloy exhibits a high retardation effect to overloads ; reasons for this good behaviour are given considering mechanical and fractographic aspects.
