Abstract:

Due to the interactions between mechanics and chemistry, Mg alloys are inevitably subjected to the combined effect of corrosion attack and cyclic loading, which eventually leads to corrosion fatigue failure. In this paper, fundamental aspects regarding the fatigue behavior of Mg alloys have been reviewed, including: (1) fatigue behavior of Mg alloys in air and aqueous media; and (2) the influence of microstructure, anodic dissolution, hydrogen embrittlement (HE), heat treatment and surface protection on fatigue behavior of Mg alloys. Moreover, some remaining unresolved issues and future targets to deeply understand the failure mechanism of corrosion fatigue have been described.

Key words: Magnesium alloys, Fatigue, Corrosion fatigue, Crack initiation, Hydrogen embrittlement
