Temperature Dependence of Low Cycle Fatigue Behavior in AZ31 Magnesium Alloy


In situ neutron diffraction has been used to investigate the deformation behaviour of extruded magnesium at room temperature, -100. °C and 150. °C. Significant differences in the active twinning/slip systems, attributed to the strong crystallographic texture and temperature dependence, were observed. Twining is the dominant deformation mode during the cyclic loading at room temperature and at cryogenic temperature. In contrast, at high temperature, additional slip planes were activated and reduction of twinning activities was observed and the deformation mode is slip-dominated.
