| Popis: | Using the nanocrystal RP-model, the state equation of the bcc molybdenum with account of size and shape was calculated. On the basis of this equation the isobaric dependence of the melting temperature on size and shape was obtained at P = 0. It is shown, that the stronger the shape of a nanocrystal deviates from the most energetically effective one, the bigger the size of the nanocrystal at the crystallization start point. Approximation of such points for various shapes made it possible to determine the size dependence of crystallization start temperature. |
