The exchange-correlation (XC) potential is treated with the generalized gradient approximation (GGA) and local density approximation (LDA). The computed ground state properties agree well with the available theoretical and experimental values. The elastic constants are obtained by calculating the total energy versus volume conserving strains using Mehl model. The electronic and bonding properties are discussed from the calculations of band structures (BSs), densities of states and electron charge densities. The volume and bulk modulus at high pressure and temperature are investigated. Additionally, thermodynamic properties such as the heat capacity, thermal expansion and Debye temperature at high pressures and temperatures are also analyzed.eninfo:eu-repo/semantics/closedAccessIntermetallicsElectronic StructureMechanical PropertiesThermodynamicPropertiesAB Initio Calculations.Article28310.1142/S0217979214500064Q2WOS:000330643000005N/A
