“…Very little is known for the alloy Nb-Ru, especially at lowtemperature [9,10,47,[233][234][235][236][237]. We do not confirm the stability of any low-temperature compound at composition NbRu, but instead find a two-phase field between Nb 3 Ru and NbRu 2 , even though a high and low-temperature phase of NbRu has been observed [233,237].…”

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.

“…The critical ordering temperature T , = 640 "C obtained in this work for Pd,Fe is somewhat higher than the value to be inferred from the room temperature measurements of quenched samples by Raub et al [3] who report that the superstructure reflections disappear in the region 500 to 600 "C. Considering the small intensity of these reflections at 600 "C (about 10% of the value a t room temperature), the agreement is satisfactory. Our results support the approximate phase diagram by Raub et al [3] who estimate that the yz field extends to about 75 atyo Pd whereas the much wider yz field (up to about 85 atyo Yd) deduced by Kussmann and Jessen [4] from magnetic measurements is not supported by our work. However, our critical ordering temperature a t 75 atyo Pd agrees well with their result.…”

Ordering of FePd alloys with compositions 75 to 95 at% Pd is studied by X‐ray diffraction of multicrystalline samples in the temperature region up to 800 °C. The lattice parameter is also measured. The critical temperature for LRO in the 75 at% sample is found to be Tc = (640 ± 10) °C. No LRO is found at any other composition, but the possibility of local order in the 80at% sample exists on the basis of deviations observed in the diffuse scattering. The results support a first order reaction for LRO in the 75 at% sample. A small contraction is observed in the lattice of the 75 at% sample at disordering, in contrast with the dilatation observed in other A3B type superstructures.

“…Another important feature of the brass coating is its good adhesion to rubber and that is employed in a tyre industry. The electrodeposition of the excellent quality brass coating from a cyanide solution was established in the middle of the 20th century [1,2], and since then researchers have been looking for an environmentally friendly cyanide-free solution which could replace the former one without loss in the quality of coating [3][4][5][6][7][8][9]. Coatings from such solutions as pyrophosphate [3,4], pyrophosphate-oxalate [5] glucoheptonate [6,7], sorbitol [8] and glycerol-based [9] have been studied.…”
