Original Abstract
This paper summarizes basic experimental results of microstructural changes during high cycle fatigue loading of AlMg alloys (EN AW-6082 and EN AW-2017). These changes are detected by using of acoustic emission (AE) method. The authors targeted the main attention on more exact identification of causes of changes of AE signal activity in the stage of fatigue damage cumulation. The method of X-ray diffraction analysis of the structure is used for explanation of this phenomenon. The results of presented experimental works indicate the connections between changes of acoustic emission signal and cyclical changes of so called mosaic blocks of the crystal structure identified by means of X-rays diffraction during fatigue loading of material.
