Schematic illustration of the confined two-dimensional prismatic platelet. (a) Modeled atomic arrangement of the h.c.p. α-Mg matrix. (b) Modeled atomic arrangement of an ideal state for the platelet without considering lattice distortion. (c) Modeled atomic arrangement of the real state for the platelet. (d) Modeled atomic arrangement for two platelets connected with a 120° angle in the matrix; the top-right inset is the corresponding three-dimensional view. The atomic arrangements (a)–(d) viewed along the [0001]α direction. (e) Atomic structure of the precipitate chain. (f) Quasi-unit cell of the platelet. (g) Three-dimensional view of the quasi-unit-cell rod. (h) Three-dimensional detail of the interface structure between the matrix and platelet. (i) Modeled atomic arrangement of the platelet in the matrix viewed along the [[11{\overline 2}0]]α direction.
