Original Abstract

The paper deals mainly with measurement and evaluation of acoustic emission signal (AE) in continues monitoring of surface strengthened wrought aluminium alloy EN AW-2017A/T4 using X-ray diffraction topography. Other models and approaches to evaluating the results of the AE signal, which are essential to identify the microscopic processes occurring in the structure of the material throughout the fatigue process are presented here. Non-destructive observation using X-ray diffraction (XRD) is focused primarily on the phase changes of mechanical properties where the AE signal showed increased activity. The main principle of the X-ray technique is to record directional distribution of mosaics blocks which are changed periodically by cyclic loading of the material. The measurements are supplemented by the record of resonant frequency changes of loading device RUMUL Cracktronic.
