“…Ab initio % Pd (Massalski [9]) result 66 to 67 Mo-Pt (Molybdenum -Platinum). The phase diagram of this alloy is known from experimental investigations and thermodynamic modeling [9,10,[201][202][203][204][205][206][207][208][209][210]277]. We confirm the stability of MoPt-B19 and MoPt 2 (with MoPt 2 prototype).…”

systems in which the ab initio method predicts that no compounds are stable). A detailed comparison to experimental data confirms the high accuracy with which ab initio methods can predict ground states. A 2 B 2 hcp superstructure for RhRu, and an A 2 B 4 hcp superstructure for RhRu 2 (Appendix (XI)). In addition, we find two new crystal structures which are not superstructures of fcc, bcc or hcp: MoZr 3 and Mo 5 Ti (for Mo 5 Ti, MoZr 5 , and Nb 5 Ru) (Appendix (XII)). II. THE LIBRARY: ALLOYS AND STRUCTURESBinary alloys. Our calculated library contains 80 binary intermetallic alloys. The alloys include the binaries that can be made from row 5 transition metals, as well as some systems with Aluminum, Gold, Magnesium, Platinum, Scandium, Sodium, Titanium, and Technetium. The alloys are: AgAu, AgCd, AgMg, where the superscript * indicates the systems in which the high throughput ab initio method predicts that no compounds are stable: 57 alloys form compounds and 23 are non compound forming.Structures and their prototypes. The library contains 176 crystal structures. Many of these have the same structure type but with different compositions of occupancies, for example, AB 3 and A 3 B (also AB and BA if the point groups of atomic positions of A and B are different), so the number of distinct prototypes is 101. The various concentrations are listed in the table below.TcZr-B2 TABLE 6: Experimentally unknown, non-identified or speculated compounds and ab initio predictions (21 entries). 48 C.

“…That was confirmed by Ocken and Van Vucht and a complete phase diagram was proposed [3]. The portion up to 55 at.% Pt has been modified according to the work of Flükiger et al [4], with the addition of e 0 phase. An assessment by thermodynamic modelling of the Mo-Pt system was compiled by Brewer and Lamoreaux [5] based primarily on the work of Flükiger et al They had confirmed the existence of the above five intermediate phases.…”

“…The revised Pt-Mo phase diagram, Fig. 1, was then proposed by Brewer and Lamoreaux [6] based on the work of many researchers [5,7]. The unmarked phase region (between 70 at.% and 80 at.% Pt) was reported by Ocken and Van Vucht [5] as tentative because of the challenges in distinguishing between the existence of a single-phase MoPt 2 and two-phase MoPt 2 plus fcc Pt-solid solution.…”
