Static displacements of Pd in the solid solution PdBy (0 <y < 0.2) as determined by neutron diffraction

X-ray diffraction analysis of the anisotropic nature of the structural imperfections in a sputter-deposited TiO2/Ti3Al bilayer

“…The static atomic displacement is due to defects with displacement fields of essentially short range nature (see, for example, Ref. [56]), such as point defects (impurity atoms, vacancies, etc.). As discussed in Section 4.2, about 6 at.% In is dissolved in the Ti 3 Al layer.…”

A time-resolved X-ray powder diffraction method to trace the decomposition of PdBy solid solutions

“…PdB 0.050 , previously used in a neutron diffraction study, was prepared similarly from 11 B [7]. Both reguli were checked for homogeneity [5][6][7].…”

“…PdB 0.050 , previously used in a neutron diffraction study, was prepared similarly from 11 B [7]. Both reguli were checked for homogeneity [5][6][7]. The powder samples (filed from the reguli) were sealed under vacuum in quartz capsules, annealed at 800°C for 5 min and subsequently quenched in water.…”

On the formation and crystal structure of the Pd6B phase

“…For an overview of the prepared alloys, see Table 1. For alloy 2 intended for neutron diffraction measurements the pure isotope 11 B was used instead of B with the natural mixture of its isotopes (about 20 at% 10 B), because 10 B has an extremely high neutron absorption cross section [28] and by its use the diffracted neutron beam intensity would decrease dramatically.…”

“…The latter may be regarded a remarkable model system for the study of the character of metallic interstitial phases. In the crystal structure of Pd[B] the B atoms occupy octahedral interstitial sites of a cubic close packed (ccp) partial structure of Pd atoms [8,10,11] in a disordered fashion, such that both the Pd sites and the octahedral sites form fcc type arrays. The maximum interstitial solubility above about 450 C in Pd [B] has been reported to correspond to an atomic fraction of $20 at% B [12], which is the largest one known for any metal-boron system [8].…”
