Interatomic interaction in interstitial solutions with fcc and bcc lattices Academic Article uri icon


  • The energy and deformation interaction in disordered interstitial solutions are determined by means of the pseudopotential method. Calculations are made for the systems Ti-C and Zr-C. Comparison of the deformation interaction energies and the Fourier transforms of the quasielastic forces has shown that in the system Ti-C the deformation interaction is greater than in Zr-C. Numerical calculations have established that filling of the z sublattice of octahedral interstices is energetically more advantageous in the bcc interstitial solution Zr-C.
