We studied total energies of various ordered structures of ${\mathrm{PdH}}_{\mathit{x}}$ (in which hydrogen occupies the octahedral sites within the fcc Pd lattice) using the pseudopotential method and a plane-wave basis within the local-density-func

First-principles electronic structure calculations based on the full-potential linear-muffin-tin-orbital method have been employed to study the contrasting effects of boron and hydrogen on the electronic structure of the L${1}_{2}$ ordered intermetal

The phase stability is studied for the \ensuremath{\beta}-phase ${\mathrm{YH}}_{2+\mathit{x}}$ system based on first-principles total energy calculations. Our study predicts that the ${\mathrm{D}0}_{22}$, ``40'', and ${\mathrm{D}1}_{\mathit{a}}$ stru

The asymmetry in the phase diagram of the H/Ru(001) system is studied by assuming a lattice gas model for the chemisorbed hydrogen and using the cluster variation method. Ground state analysis of the ordered structures shows that the effective pair i

Microalloying studies have shown1 that doping with certain impurities, which prefer to segregate towards grain boundaries, can significantly improve the ductility of polycrystalline Ni3Al.2 The addition of only 0.05 wt% (0.25 at%) of boron increases
