Abstract
Corrosion fatigue behaviors of creep-resistant magnesium alloys DieMag422 and AE42 were characterized by means of lifetime- and process-oriented approaches. Fatigue properties of both materials were assessed in constant amplitude tests at several adjusted corrosion rates. Deterioration and cracking mechanisms were identified and monitored by means of corrosion potential response analysis during constant amplitude tests. Reduction of corrosion fatigue strength could be quantitatively correlated with adjusted corrosion rates. Analysis of corrosion potential response revealed characteristic deterioration and cracking mechanisms for LCF and HCF regime.
