In this research paper we have discovered the structural phase transition and elastic properties of transition metal carbides (TaC and HfC). Phase transition pressures are associated with a sudden collapse in volume showing the incidence of first order phase transition. At ambient condition the present compounds exhibit rock salt (NaCl) structure, they transform into cesium chloride (CsCl) structure under high pressure. The phase transition pressures and associated volume collapses obtained from present potential model show a generally good agreement with the available literature. The elastic constants and bulk modulus are also reported for the present compounds.
