Fatigue corrosion cracking in a deep-drawn component

Fatigue corrosion cracking is the term used when a fatigue crack progresses with the support of a corrosive attack. In the typical fracture pattern, feather-like patterns are superimposed with fatigue striations. Unlike stress corrosion cracking (static loading), fatigue corrosion cracking does not require a specific aggressive medium for the particular material. In the present example, a deep-drawn component made of DC01 failed under minimal load, the cracks originated from a sharp-edged bending position.
