Original abstract

This paper deals with evaluation of degradation processes, which occur at cyclic loading of samples of Al alloy EN AW-2017/T4. NDT procedure – acoustic emission (AE) method was used for detection of microstructure changes during stages of fatigue damage accumulation and micro-cracks initialisation. This measurement was completed with analysis of loading frequency changes of the fatigue test device. AE signal records obtained with use of the newly developed AE analyser with continual recording of signal are commented and showed other parameters of AE sample in detail.

Článek se zabývá možnostmi hodnocení degradačních procesů, které se objevují při cyklickém zatěžování zkušebních vzorků z Al slitiny EN AW-2017/T4. Pro detekci změn mikrostruktury v průběhu akumulace poškození a iniciace mikrotrhlin byla využita metoda akustické emise. Toto měření bylo doplněno analyzou změn zatěžovací frekvence zkušebního zařízení. Jsou ukázány a detailněji popsány další parmetry signalu AE, získané s pomocí nově vyvinutého analyzátoru IPL s kontinuálním záznamem a zpracováním signalu AE .
