Experimental investigation and thermodynamic modeling of the Ni–Al–Ru ternary system

Thermal and physical properties of Al–Ni–Ru–M alloys

“…As mentioned earlier, there exists a large body of experimental and theoretical work on the base Al-Ni-Ru system [7][8][9][10][11]. In addition, a previous application of the BFS method to this system [24] has proven to be in agreement with such work, thus providing confidence on its parameterization and providing the necessary foundation for the results presented in this work.…”

“…Due to the extensive nature of previous work on this system, we refer the reader to Refs. [5][6][7][8][9][10][11]15,16] for the appropriate background. For the purpose of the current investigation, we first examine the changes in properties of Al-Ni-Ru alloys within their B2 field.…”

“…A substantial amount of theoretical and experimental work is available for the base RuAl and NiAl alloys [3][4][5][6][7][8][9][10][11]. This work, added to studies of the role of alloying additions to these fundamental binary systems provides an excellent foundation to the extension to more complex systems.…”

Study of the Ni-rich multi-phase equilibria in Ni–Al–Pt alloys using the cluster/site approximation for the face-centered cubic phases

“…The term thermodynamic description denotes that the thermodynamic model parameters for all the phases in question are known as a function of composition and temperature at a constant pressure of 1 bar. In other words, a preliminary thermodynamic description of Ni-Al-Pt is obtained from those of its three constituent binaries, Ni-Al [5], Ni-Pt [6] and Al-Pt [6] as well as diffusion couple data reported by Gleeson et al [1,7] in Ni-Al-Pt. We selected fourteen alloys for experimentation: four in the two-phase equilibrium of c and c 0 for study at 1433 K, five in the same two-phase equilibrium for study at 1523 K and five in the two-phase equilibrium of c 0 and b for study at 1523 K. In this study, the modified cluster/site approximation (CSA) is used to describe the thermodynamics of the disordered fcc-A1 solution phase and the various ordered intermetallic phases such as the L1 2 and L1 0 phases [8][9][10][11][12][13][14][15][16][17][18][19].…”

Ordered phases in ruthenium binary alloys from high-throughput first-principles calculations

“…Similar issues were addressed for ruthenium-doped Nb-based superalloys 46 , as well as the relative stability of the several phases of NbRu shape memory alloys [47][48][49][50] . The defect structure of NiRu and NiRuAl alloys was modelled by ab initio methods 51 and their phase diagram was investigated by thermal modelling assisted by ab initio calculations 52,53 . Ru(0001) was shown to be a good catalyst for epitaxial growth of graphene 54 .…”
