Original Abstract

In this paper are presented two nondestructive methods, acoustic emission (AE) and X-ray diffraction topography (XRD), which are used for investigation of damage cummulation and crack creation stages of fatigue process in strengthened wrought aluminium alloys EN AW-2017A/T4 and EN AW-6082/T6. All tests were performed on the resonant testing machine RUMUL Cracktronic 160 under the current recording acoustic emission signal. The X-ray diffraction was focused especially on the stages of material properties changes, where the AE signal had significant activity. The results show connection between the change in AE signal parameters and changes in microstructure, observed by X-ray diffraction technique
