Abstract

The low-cycle and high-cycle fatigue behavior of the Mg-base wrought alloy AZ31 is investigated in the temperature range 20– 300 °C using total-strain-controlled push – pull tests. It is shown that the mechanical properties of the material are substantially influenced by the direction dependent formation of deformation twins and resulting deformation asymmetry. As a consequence tensile mean stresses develop during total-strain-controlled fatigue tests without mean strain.

Abstract

Das Verformungsverhalten der Mg-Basis-Knetlegierung AZ31 bei schwingender Beanspruchung sowohl im Kurzzeit- als auch im Zeitfestigkeitsbereich wurde bei Temperaturen von 20– 300 °C untersucht. Dazu wurden totaldehnungskontrollierte Zug– Druck-Wechselverformungsversuche durchgeführt. Die Experimente zeigen, dass die beobachteten mechanischen Eigenschaften stark von den auftretenden Unterschieden im Verformungsverhalten zwischen Zug- und Druckbeanspruchung geprägt sind. Dies ist auf die Richtungsabhängigkeit der Bildung von Verformungszwillingen zurückzuführen. Als Folge treten bei mitteldehnungsfreier totaldehnungskontrollierter Beanspruchung Zugmittelspannungen auf.

Keywords: Cyclic deformation behavior; Fatigue; strain-controlled; Magnesium wrought alloy AZ31
