Abstract ：
Effects of pressure on lattice parameters, electronic, thermodynamic and mechanical properties of the fully ordered Ti2AlNb orthorhombic phase were studied using first-principles calculations based on density functional theory (DFT). The bonding nature for ordering orthorhombic Ti2AlNb was revealed quantitatively through the electronic structure analyzing. The external pressures play limited roles in the elastic anisotropy of the alloy due to the outstanding dynamical and mechanical stabilities under pressure. However, the shear modulus of O phase manifests anisotropic, where {010} shear planes are the easiest planes to cleave among the principal planes under all pressures. The heat capacities, volume expansions and thermal expansion coefficients were calculated using the quasi-harmonic approximation model based on the phonon dispersion curves. Meanwhile, the bulk modulus, Young's modulus, shear modulus and the hardness are promptly enhanced under pressure. The predicted results give hints to design Ti2AlNb-based alloy as high-pressure applications.

Abstract ：
The site occupy behaviors of NbCr2-based C15 Laves phase alloyed with M (M = Ti, V, Mo and W) and Hf0.25V0.6NB0.15 C15 Laves phases at finite temperature were predicted using sublattice model, where the Gibbs free energies at finite temperature were obtained by quasi-harmonic approximation(QHA) model. The predicted results were compared with the available experimental results and other calculated results. The prediction was improved compared with early thermodynamic model, where the enthalpies of formation of the end-members at 0 K were accounted only. For NbCr2-based C15 Laves phases, Nb atom prefers to occupy 8a subattices, Cr atom prefers to occupy 16d subattices, and the third alloying element Ti prefers to occupy 8a subattices, which is not affected by the chemical composition and temperature, on the contrary, the site preferences of the third alloying elements Mo, V and W depend sensitively on the chemical composition and temperature. For the selected ternary Hf0.25V0.6Nb0.15 C15 phase with available experimental data, the site fraction of Nb element occupying the 8a sublattices decreases slowly with the increase of temperature, the calculated site occupying configuration at 1473 K is (Hf0.750Nb0.240V0.001)(8a)(Nb0.105V0.895)(16d), which is close to the available experimental result.

Abstract ：
Ti2AlNb-based alloy with a dominated orthorhombic phase is one of the most promising high-temperature structural materials. In this work, the equilibrium volume, elastic, and thermodynamic properties of the ordered O phase with stoichiometric Ti2AlNb were predicted under different temperatures using first-principles calculations based on density functional theory combined with quasi-harmonic approximation (QHA). With the increase of temperature from 0 to 1300 K, the elastic properties decrease moderately and the bonding strength weakens slightly. The intrinsic properties of the Ti2AlNb O phase are ductile at all temperature considered. In order to explore the evolution mechanism of the temperature-dependent elastic properties further, the density of state (DOS) has been analyzed. The stoichiometric Ti2AlNb O phase shows good high-temperature mechanical and thermal stability, which is a kind of potential high-temperature alloy applied in aeronautics industries.

Abstract ：
ZnZrAl2 is a kind of heterogeneous nucleation to promote the refine of grain of ZA43 alloy. ZnZrAl2 intermetallic is also considered as a candidate for superalloys. The crystal lattice structure, alloy thermodynamics and mechanical properties of ZnZrAl2 intermetallic compound were investigated by ab initio calculations based on density functional theory (DFT). In particular, the site preference of atoms in different sublattices was predicted based on alloy thermodynamics. At ground state, the most stable structure is L1(2) structure with sublattice model (Zn)(1a)(Zr0.3333Al0.6667)(3c) or (Zr)(1a)(Zn0.3333Al0.6667)(3c), and the occupying preferences of Zn, Zr and Al atoms are independent with the increasing temperature. The bulk, shear, Young's modulus and the Poisson's ratio of the L1(2) structure ZnZrAl2 were calculated based on the site occupying configurations. The results show that ZnZrAl2 is a brittle material in nature. Electronic structures analysis revealed that Al-Zr atoms possess a covalent bonding character, while the Zn-Zr atoms have a metallic bonding character. ZnZrAl2 has stable mechanical properties at high temperature. The grain refinement effect of ZnZrAl2 precipitates in Zn-Al alloys were discussed based on crystal lattice match theory.
