抄録

We investigated the influence of a change in the stacking sequence of the close-packed plane in a Mg₁₂ZnY long-period stacking ordered (LPSO) phase on its mechanical properties. A 14H-typed LPSO-phase crystal was fabricated by annealing a directionally solidified (DS) crystal with a 18R-typed LPSO-structure at 525°C for 3 days, and the temperature dependence and orientation dependence of the yield stress were examined via compression tests. (0001)⟨11\\bar20⟩ basal slip was identified as a dominant deformation mode, and deformation kink bands were formed under compression in the case of suppression of basal slip motion. The deformation mechanism of the 14H-typed LPSO-phase is almost similar to that of the 18R-typed LPSO-phase, even though a slight difference was observed at temperatures above 300°C.
