The three binary systems Mg–Ni, Ca–Ni and Mg–Ca have been re-optimized. A self-consistent thermodynamic database of the Mg–Ni–Ca system is constructed by combining the optimized parameters of these three constituent binaries. Lattice stability values are not added to the pure elements Mg-hcp, Ni-fcc, Ca-fcc and Ca-bcc to construct this database. The Redlich–Kister polynomial model is used to describe...
The H–La–Ni system has been assessed according to the CALPHAD method. To this purpose, an assessment of the La–Ni binary system has been taken from the literature, while the H–Ni system has been partially reassessed with respect to the liquid phase, in order to be consistent with generally used lattice stability of liquid hydrogen. A first assessment of binary H–La system has been carried out in this...
In this work, a powder metallurgy procedure for the preparation of bulk hydrogen storage alloys based on MgH 2 is presented. To meet the requirements of high specific surface area, high porosity and microstructural stability, all desirable features for this sort of material, a powder mixture with the following composition MgH 2 –15Nb–2B–1C has been ball-milled to reduce down to a few...
A thorough review and critical evaluation of phase equilibria and thermodynamic data for the phases in the Mg–Ni–Y ternary system have been carried out over the entire composition range from room temperature to above the liquidus. This system is being modeled for the first time using the modified quasichemical model which considers the presence of short range ordering in the liquid. The Gibbs energies...
A thermodynamic study on the Mg–Al–Li–Na–H system is conducted in this work in order to investigate its hydrogen storage properties. For that purpose, a thermodynamic database is constructed using the CALPHAD technique. In this work, Li is added to the previously studied Mg–Al–Na–H system and the related binaries (Li–Mg, Li–Na) and ternaries (Al–Li–Mg, Al–Li–H, Li–Mg–H) are reassessed using the Compound...
