%X A model without any adjustable parameters, describing the dependence of melting temperature on grain size, was established. It is demonstrated that melting temperature of metallic nanocrystals decreases as its size decreases. When the size of nanocrystals reaches its minimum, the melting temperature of the nanocrystals reaches its lowest value and the corresponding melting entropy is zero. With this model, the calculated melting temperatures of in and Pb nanocrystals and Fe thin film are in correspondence with the experimental results. The melting temperatures of magnetic recording nanocrystals of Fe, Co and Ni elements are predicted.
