Abstract

In this study, the detection of fatigue damage accumulation and hydrogen embrittlement in 7075 alloy was confirmed using the eddy current method. Fatigue damage and hydrogen charging were accumulated in notched specimens, and then changes in amplitude and phase were measured in the specimens using eddy current testing. The maximum values of the signals were observed at an area where fatigue damage and hydrogen charging were accumulated. The experimental results correlated with accumulation of fatigue damage and hydrogen charging in the specimens. Therefore, the possibility of using this method for the quantitative evaluation of fatigue damage accumulation and hydrogen embrittlement in aluminum alloys is presented.
