What is a Crack Initiation? - Definition from Corrosionpedia

Crack initiation is a process that forms cracks on the surface of a material. The primary reason for the formation of cracks on any surface is fatigue. Fatigue leads to progressive and localized structural damage when any material experiences cyclic loading.Variation of the Corrosion Behavior Prior to Crack corrosion fatigue crack initiation behavior of stainlessAbstract.

Such a plateau in behavior with increasing corrosion severity was similar to what has been reported previously by Burns, et al. 4-5,19,21 The near-constant initiation life can be related to the dominance of the interaction of localized corrosion features with underlying microstructure discontinuities to nucleate fatigue crack, as detailed in corrosion fatigue crack initiation behavior of stainlessGalvanic Corrosion Induced Fatigue Crack Initiation techniques for the determination of crack initiation location are presented. 2.

Corrosion Fatigue - an overview | ScienceDirect Topics

Although in ordinary fatigue, crack initiation is impeded by a high tensile strength, this does not apply to corrosion fatigue because in this case, it is the corrosion that initiates cracking. Moreover, once initiated in a metal, a crack will propagate faster with rising tensile strength.Bending Fatigue Behavior of 316L Stainless Steel up to corrosion fatigue crack initiation behavior of stainlessEffect of microstructure on the crack initiation and early propagation mechanism in the very high cycle fatigue (VHCF) regime was studied in 316L stainless steel (316L SS) by atomic force microscope (AFM) and electron back scattered diffraction (EBSD).
