In situ monitoring of dislocation, twinning, and detwinning modes in an extruded magnesium alloy under cyclic loading conditions

Di Xie et al.

Summary: This study examines the microscopic deformation mechanisms of an extruded, precipitation-strengthened AZ80 magnesium alloy under strain-controlled low-cycle fatigue using in situ neutron diffraction measurements. The results show that plastic deformation is primarily controlled by alternating {10.2} extension twinning and detwinning mechanisms. The complex evolution of dominant deformation mechanisms in this alloy is influenced by initial texture, precipitation strengthening, and load sharing of different grain families and phases, with elevated dislocation activities believed to contribute to its relatively poor low-cycle fatigue lifetime compared to other magnesium alloys.

Micromechanical origin of the enhanced ductility in twinless duplex Mg-Li alloy

Di Xie et al.

Summary: Through real-time neutron diffraction measurements, it was found that the enhanced ductility of duplex Mg-Li alloys is attributed to the early yield of BCC beta-Li phase and the sequential activation of basal and pyramidal a slip systems in HCP alpha-Mg phase, which promotes overall work hardening rate and relieves Mises constraint for deformation compatibility. No obvious twinning activities were observed, resulting in symmetric hysteresis loops during a full loading cycle within +/- 1% applied strain.
