Electrochemical-Based Characterization of the Corrosion Fatigue Behavior of Creep-Resistant Magnesium Alloys DieMag422 and AE42

Abstract:

The corrosion fatigue behaviors of the creep-resistant magnesium alloys DieMag422 and AE42 were characterized by means of constant amplitude tests in sodium chloride solutions using corrosion potential and strain measurements. Characteristic microstructural deterioration and cracking processes in low and high cycle fatigue regime could be monitored on the basis of characteristic corrosion potential responses, which were investigated in detail by means of combined analysis of corrosion potential and total strain oscillations.
