Comparison of Acoustic Emission Signal and X-ray Diffraction at Initial Stages of Fatigue Damage
Original language description
The contribution treats the evaluation of degradation processes appearing during the cyclic loading of the samples from Al alloys EN AW-2017/T4 and EN AW-6082/T6. Two NDT methods have been applied in this case, namely the acoustic emission (AE) and the X-ray diffraction used to detect the microstructural changes in the material during the fatigue damages as well as to report the microcracks appearing afterwards. These measurements have been completed with reports of changes to the loading (resonance) frequency coming from fatigue loading equipment. Moreover, the article describes the records of AE signal coming from an AE analyser with full scan of signal as it has been newly developed. The main advantage of this type analyser (compared with AE measuring systems currently used) is continuous sampling and full (uninterrupted) signal saving data.
