From the journal Materials Testing

Abstract

In this study, the fatigue tests were conducted on the AA6082 alloy sheets both in tempered (softened) and in T6 temper conditions, and the results obtained were examined. In this context, the aim of this study was to determine the effect of the tempering condition on the fatigue characteristics of the alloy. Microstructural evolutions in the tempered samples were examined using SEM (scanning electron microscopy) and interpreted. The investigations have revealed that the tempering condition significantly affects the fatigue life of the alloy.

Kurzfassung

In der diesem Beitrag zugrunde liegenden Studie wurden Ermüdungsversuche mit Blechen der Aluminiumlegierung AA6082 im Lieferzustand (T651) und im Wärmebehandlungszustand T6 durchgeführt und die Ergebnisse entsprechend untersucht. Hierzu wurden die mikrostrukturellen Veränderungen mittels Rasterelektronenmikroskopie (REM) dargestellt und interpretiert. Die Ergebnisse zeigen, dass sich die Wärmebehandlungsbedingungen signifikant auf die Lebensdauer der Legierung auswirken.
