Original abstract

This 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.

Czech abstract

V příspěvku jsou popsány degradační procesy, které se objevují před vznikem krátkých trhlin při cyklickém zatěžování vzrorků ze slitin EN AW-2017/T4 a EN AW-6082/T6. Byly použity dvě NDT metody – akustická emise a RTG difrakce. Měření je doplněno sledování změn frekvence zatěžování elektrorezonančních zatěžovacího stroje.
