Pressure-induced Structural Phase Transitions in Ti sub(1-x)Zr sub(x)C Solid Solution

In present paper we have analyzed the relative Structural stability and pressure dependent B1 arrow right B2 structural phase transformations in Ti sub(1-x)Zr sub(x)C solid solution. For the present work, we have used three-body force potential model which includes the long range as well as short range interactions, where Coulomb and three body interactions are the contents of long range part and the van der Waals multipole interactions and the Hafemeister and Flygare overlap repulsive interactions (effective up to the next nearest neighbors) makes the short range part. The calculated transition pressures are 490, 461, 431, 402 and 372 GPa for TiC, Ti sub(0.75)Zr sub(0.25)C, Ti sub(0.50)Zr sub(0.50)C, Ti sub(0.25)Zr sub(0.75)C, and ZrC compounds respectively.
