First approximation of ternary phase diagram was calculated and confronted with experimental data in Mg-rich corner of Mg-Li-Sc system. It was found that predicted phase diagram reasonably agreed with experimental evidence.doi:10.1016/j.jallcom.2018.12.189Dutkiewicz, JanRogal, ŁukaszKalita, DamianFima, PrzemyslawElsevier ScienceJournal ...
According to the Mg-Li phase diagram (Fig. 12.7), the alloys exhibit two phase structures ofα(hexagonal close packed (hcp)) Mg-rich andβ(body-centered cubic (bcc)) Li-rich phases at room temperature when 5-11% Li is added to magnesium. Further additions of Li (more than 11%) can...

For example, as can be seen in the Mg-Li phase diagram [32], only a small amount of lithium leads to the stabilization of a solid solution of magnesium in lithium with a body-centered cubic crystalline structure, which is in contrast to the hexagonal close-packed structure of magnesium [...

[4] referred to the existence of a ternary phase in the Cu-Li-Mg system: Cu8Li2Mg15 with an orthorhombic structure (a = 0.524 nm, b = 0.899 nm, and c = 5.433 nm). Hämäläinen et al. [3] assessed the phase diagram of the system. Figure 1 presents two verti- cal ...
The schematic representation and the energy diagram of the QLED devices are shown in Fig. 2. We used a double hole transport layer (HTL) made of poly-TPD/PVK to form a stepwise change of energy levels for efficient hole injection into the QD emissive layer. To study the effects of dopant...
(38–54 nm) pure-phase spinel cubic structure (Fd-3¯m). Also, the particle size analysis results demonstrate the narrow distribution of their particle sizes, which range from 10 to 33 nm. The impact of Mg2+ion concentration on the thermal, elastic, magnetic, and optical properties ...
