Application of NDT Procedures for Identification of Fatigue Life Stages of AlMg Alloys

摘要：

This paper describes some basic exposures of Al and Mg alloys (EN AW 6082, EN AW 7075, and AZ 91) behaviour change during high cycle fatigue loading which were detected using some NDT methods. Changes of loading frequency and acoustic emission signal were used for identification of different stages of fatigue process. However it is very difficult to exactly specify the reason of AE signal change or the loading frequency. That is why the X-ray diffraction analysis of the structure method was used. This method can further clarify some processes in the loaded material.
