The band structure calculations are performed on the intermetallic compounds Rh{sub 3}V and Rh{sub 3}V{sub x}(Al){sub 1-x} by Full Potential Linearized Augmented Plane Wave(FP-LAPW) method. Total energies are calculated as a function of volume and fitted to Birch-Murnaughan equation of state to find the lattice parameter and the other ground state properties. The ductility of these compounds has been analyzed using Cauchy’s Pressure, Pugh Rule and Poisson’s ratio. From this study we observed that Rh{sub 3}V is brittle while its alloy Rh{sub 3}V{sub 0.875}Al{sub 0.125} is ductile. Electron density plots are illustrated and compared.
