Magnesium (Mg) alloys have recently attracted great attention for potential biodegradable implant applications. Cracking/fracture of metallic implants under the simultaneous action of corrosion and mechanical stresses, viz., corrosion fatigue (CF) or/and stress corrosion cracking (SCC) is an obviously critical criterion before any new material could be deployed as implants. This article presents a review of the available literature on CF of Mg alloys in corrosive environments including simulated-body-fluid (SBF) and the associated fracture mechanism, and identifies the knowledge gap. A brief overview of the mitigation strategies to combat the possible CF failures of Mg alloys is also presented.
