The information of stable solid phases and the models used in the Ho X (X: Cu, Mo, V) systems  are listed in Table 1. 2.1. Solution phases Gibbs free energies of the solution phases of (liquid and hcp, fcc and bcc phases) in an A B system, corresponding to the Cu Ho, Ho Mo and Ho V systems, were described by the subregular solu-

Structure and superconductivity in ternary systems of compounds
established that certain particular crystal structure of a binary or ternary (intermetallic or chemical) compound is very conducive to give rise to high T~ superconductivity. The beta-tungsten (A3B or A15) structure adopted by a large number ofintermetallics is the well-known example.

and phase equilibria studies in the Fe‐C binary system at pressures above 130 GPa [Lord et al., 2009].  On the basis of systematics of compressibility in intermetallic phases, Wood  assumed a bulk modulus K 0 = 174 GPa and its pressure derivative K′ 0 = 5.1 for Fe 3C.

identiﬁed some new phases such as Al 3Ce.hR12, AlCe 2.oP12, and Al 3Nd.hR12 in theAl-Ce andAl-Nd sys-tems and assigned the crystal structures based on FP calcu-lations. In light of their results, it is reasonable to ask the following questions: Are there any phases inappropriately treated or any phases missing in the other Al-RE RE=rare

Metastable phases produced by quenching from HT → avoid surface oxidation and study the bulk We were interested in possible Zr/Nb or Ti/V atomic ordering in the binary Ω phase. We needed reliable phase fractions to study phase coexistence in the diagram, not possible at Centro Atómico with a conventional diffractometer in this kind of samples.

phases have been observed to exist in the group V elements Sb and Bi, and the group N-VI compounds PbS, PbSe, and PbTe. Our high-resolution angle-dispersive data, collected using im age plates from samples within diamond anvil high-pressure cells, has shown that one high-pressure structure type is common to all five materials we have studied.
Importance of the atom-pair bond in metallic alloying - arXiv
intermetallic compounds in binary systems has also interested scientists for a long time and they have worked essentially using structural maps with different pseudo-potential-derived or empirically derived parameters as coordinates5-9. Intermetallic compounds with different crystal structures were separated into different regions on such maps.
