Fatigue cracks initiated from the near-surface of base metal and propagated by the formation of fatigue striations together with secondary cracks. reach officeStriations are often produced in high strength aluminium alloys. In these alloys, the presence of water vapour is necessary to produce ductile striations, although too much water vapour will produce brittle striations also known as cleavage striations. Brittle striations are flatter and larger than ductile striations produced with the same load. There is sufficient water vapour present in the atmosphere to generate ductile striations.
