Deformation behavior of two Mg-Zn-Y magnesium alloys, having a different fraction of the long-period-stacking-ordered (LPSO) phase, has been investigated at room temperature and 200$$^{circ}$$C by a combination of ${it in situ}$ neutron diffraction (ND) and acoustic emission (AE) measurements. The results indicate that the twinning in the magnesium matrix and the kinking in the LPSO phase strongly depend on the composition of the material and the testing temperature. Further, active deformation mechanisms and particularly the load transfer from the magnesium matrix to the LPSO phase define the mechanical properties of the investigated alloys.

Investigation of the evolution of the microstructure in the directionally solidified Long-Period Stacking-Ordered (LPSO) magnesium alloy as a function of the temperature

The influence of the LPSO-phase orientation and the temperature on the deformation mechanisms of directionally solidified Mg-Zn-Y magnesium alloy has been investigated by neutron diffraction and acoustic emission (AE) technique. The results indicate that the kinking mechanism and activation of non-basal slip are significantly temperature and orientation dependent with respect to the loading axis.
