| Title
A single sentence description.
|
EAM potential (LAMMPS cubic hermite tabulation) for the Ni-Al system developed by Purja Pun and Minshin (2009) v005 |
|---|---|
| Description
A short description of the Model describing its key features including for example: type of model (pair potential, 3-body potential, EAM, etc.), modeled species (Ac, Ag, ..., Zr), intended purpose, origin, and so on.
|
An improved EAM alloy potential describing properties of several phases of the Ni-Al system. Obtained by crossing the previously developed EAM potentials for pure Ni and Al (Y. Mishin, D. Farkas, M.J. Mehl, and D.A. Papaconstantopoulos, "Interatomic potentials for monoatomic metals from experimental data and ab initio calculations," Phys. Rev. B 59, 3393 (1999)). The potential has been tested for many properties, including the melting temperatures of several phases. |
| Species
The supported atomic species.
| Al, Ni |
| Disclaimer
A short statement of applicability which will accompany any results computed using it. A developer can use the disclaimer to inform users of the intended use of this KIM Item.

The paper reporting on this potential (G.P. Purja Pun and Y. Mishin, "Development of an interatomic potential for the Ni-Al system," Phil. Mag. 89, 3245 (2009)) contains an error in Table 6. The generalized stacking fault energies in Ni3Al listed in this table are incorrect. The correct energies computed with the new potential are (in J/m2): APB (111) 180 CSF (111) 229 SISF (111) 21 APB (100) 20 |

BCC Lattice Constant
This bar chart plot shows the mono-atomic body-centered cubic (bcc) lattice constant predicted by the current model (shown in the unique color) compared with the predictions for all other models in the OpenKIM Repository that support the species. The vertical bars show the average and standard deviation (one sigma) bounds for all model predictions. Graphs are generated for each species supported by the model.

Cohesive Energy Graph
This graph shows the cohesive energy versus volume-per-atom for the current mode for four mono-atomic cubic phases (body-centered cubic (bcc), face-centered cubic (fcc), simple cubic (sc), and diamond). The curve with the lowest minimum is the ground state of the crystal if stable. (The crystal structure is enforced in these calculations, so the phase may not be stable.) Graphs are generated for each species supported by the model.

CohesiveEnergyVsLatticeConstant__TD_554653289799_002
This Test Driver uses LAMMPS to compute the cohesive energy of a given monoatomic cubic lattice (fcc, bcc, sc, or diamond) at a variety of lattice spacings. The lattice spacings range from a_min (=a_min_frac*a_0) to a_max (=a_max_frac*a_0) where a_0, a_min_frac, and a_max_frac are read from stdin (a_0 is typically approximately equal to the equilibrium lattice constant). The precise scaling and number of lattice spacings sampled between a_min and a_0 (a_0 and a_max) is specified by two additional parameters passed from stdin: N_lower and samplespacing_lower (N_upper and samplespacing_upper). Please see README.txt for further details.
