An ab initio method with mixed-basis norm-conserving non-local pseudopotential has been employed to study the geometry and electronic properties of transition metal aluminide NiAl. The structure-energy phase diagram, band structure, electronic density of states and valence electron charge density contours have been show n. T he crystal structure, lattice constant, bulk modulus and band structures obtained by our calculation are in good agreement with other theoretical results and experimental data.
