| Abstract: | The relation beween the elastic constants and the force constants for B1-MoN and B1-WN crystals has been derived by means of group theory method. According as the equilibrium laitic constants and the elastic constants obtained from LMTO-ASA method, their force constants and phonon dispersions were calculated using first principle approach. |
