The recrystallization kinetics of a wrought magnesium alloy plate (AZ31B) was studied as a function of loading path, applied strain, and temperature using in-situ high-energy synchrotron x-ray diffraction (S-XRD). First, the Mg alloy was deformed to various strain levels (15%, 20%, 30%) along three tensile orientations (with the tensile axis parallel to ND, 45º to ND, and TD) and along one compression orientation (along TD). Then the deformed specimens were in-situ annealed for 120 minutes at different temperatures (200, 250, 300, and 350°C). By means of single peak fitting, evolutions of grain size and strain were measured from the changes in diffraction peak profiles, from which the recrystallization kinetics was studied. We will discuss potential effects of the changes in dominant deformation mechanisms (from prismatic slip within extension twin, basal slip, to prismatic slip) on the recrystallization behavior and the final microstructures.
