Structural stability of NiAl with the L10 structure and local lattice ...
Nov 1, 2005 · The lattice constant at the minimum is a=2.85 Å while the experimentally measured lattice constant of the NiAl alloy in the B2 structure is 2.89 Å. Our result is consistent with the experimental observations that the B 2 phase appears at the stoichiometry of NiAl.
Nickel aluminide - Wikipedia
Nickel aluminide refers to either of two widely used intermetallic compounds, Ni 3 Al or NiAl, but the term is sometimes used to refer to any nickel–aluminium alloy.

Jan 1, 2018 · It is primitive cubic Bravais lattice with two atoms per unit cell that can be divided into two distinct sublattices (alpha and beta) formed by Ni at the corners (0,0,0) and Al atoms in the body-centered positions (1/2,1/2,1/2) at stoichiometric compositions.
Ultrastrong steel via minimal lattice misfit and high-density ... - Nature
Apr 10, 2017 · We create a class of steels, strengthened by Ni (Al,Fe) precipitates, with a strength of up to 2.2 gigapascals and good ductility (about 8.2 per cent).
Atomic size effects in Ni–Al based solid solutions
Jan 1, 2001 · Using published data for the NiAl lattice parameter as a function of stoichiometry, we were able to determine the volumes of Ni and Al atoms, and of Ni vacancies in NiAl. By measuring the lattice parameters of NiAl–Ti alloys we were able to calculate an atomic size factor of +0.34 for Ti in NiAl.
describes lattice properties of Ni 3Al, point defects, planar faults, as well as the c and c0 fields on the Ni–Al phase diagram. The potential is applied to calculate the energies of coherent Ni/Ni 3Al interphase boundaries with three different crystallographic ori-entations.
The atomic structure of NiAl (a), and simplified lattice model of NiAl ...
The crystal structures, lattice parameters, volumes, elastic constants, bulk moduli and shear moduli of the binary NiAl and Ni3Al alloys have been predicted by taking the first-principles...
Modeling of lattice parameter in the Ni-Al system
Using this model, the lattice parameters of the γ and γ′ phases in the Ni-Al system were analyzed and the model parameters were evaluated. The calculated lattice parameters and mismatches show good agreement with existing experimental data.
Phase Separation and Lattice Misfit in NiAl(β 1 )–Ni 2 AlTi( H …
The lattice misfits at interphase interfaces, NiAl(B2)–Ni 2 AlTi(L2 1) and Ni 2 AlTi(L2 1)–NiTi(B2), in a pseudobinary NiAl(B2)–NiTi(B2) system have been estimated by transmission electron microscopy.
