While conventionally, only point-to-point (two-terminal) solutions were possible with an HVDC link, this emergent research paradigm was seeking to interconnect more than two terminals via HVDC links to create multi-terminal HVDC systems [11, 12, 13].
These compounds are surrounded by a Mg-rich matrix, possibly composed of glassy regions and a Mg-based terminal solid solution.
In [14], the terminal solid solutions were considered substitutional.
All the terminal solid solutions were remodeled using the compound energy formalism.
At 355 K, two biphasic regions appear, with terminal solid solutions stable only for 0 ⩽ x ⩽ 0.26 and 0.66 ⩽ x ⩽ 1.
Since this system is used for hydrogen storage purposes, the terminal solid solutions are considered interstitial and are adjusted in this work.
Unit cell parameters and densities were measured for the terminal solid solutions of the late transition metals showing the fcc structure (α-Co, Rh, Ir, Ni, Pd, Pt) with boron and partly with carbon.
Because different models are used in this study for the liquid phase (MQM) and for the terminal solid solutions than previous assessments [13, 18, 19], the system is reassessed in the present work.
Terminal solid solutions are modeled in this work using the compound energy formalism, as hydrogen atoms occupy the interstitial positions in the solid phases fcc-Al, hcp-Mg, and bcc-Na.
The constant-terminal-pressure solution is designed to provide the cumulative flow at any particular time for a reservoir in which the pressure at one boundary of the reservoir is held constant.
