Abstract:
The technique for estimating the interfacial free energy of transition-metal nanocrystals and its anisotropy at the interface with their melts has been developed. The expression for the coordinate of the Gibbs' interface, which takes into account the size dependence, has been derived. The interfacial free energy of crystal faces at the interface with the related melts of monomorphic 4$d$ and 5$d$ metals decreases nonlinearly with a decrease in the nanocrystal size and, at a certain size, disappears. At the nanocrystal radius of more than 10 nm, the interfacial free energy of the faces approaches that for a macrocrystal. The temperature dependence of the interfacial free energy at the crystal–melt interface is almost linear. The technique developed is shown to be in agreement with the known experimental data for mono- and polycrystals and applicable for estimating the orientational, temperature, and size dependences of the interfacial free energy at the interfaces of nano-, micro-, and macrocrystals with their melts.
