Characteristics of Acoustic Emission during Fatigue of As-Rolled AZ31B Magnesium Alloy
The acoustic emission (AE) detected during the fatigue process in an as-rolled magnesium alloy AZ31B was analyzed. Measurements were made during fatigue in air as well as in aqueous 0.1% NaCl solution. Three stages of fatigue were detected with AE. It is concluded that plasticity, crack extension or friction was the main AE sources during fatigue.
