The present paper reports the structural stability, pressure-induced phase transition, and thermophysical properties for refractory metal nitrides (viz: TiN, ZrN, HfN, VN, NbN, and TaN) computed using a three-body force potential model. The structural phase transitions from a parental NaCl (B1) type phase to the most stable CsCl (B2) type phase has been observed in the pressure range 162-370 GPa. Study includes the computation of thermophysical properties (U, f, θ_D, υ_0,γ, β, α_V/ C_V), where some of the properties are being reported for the first time on these materials.
