A. B. Melnick and V. K. Soolzhenko Melting in nanoclusters and a bulk of aluminium is modelled by means of molecular dynamics method. The melting temperature is revealed nonlinearly dependent on the aluminium-cluster size. The melting transformation is described as a percolation transition, which is finished when the fraction of solid-state atoms passes down the percolation threshold. Key words: crystal, liquid, cluster, molecular dynamics, percolation. https://doi.org/10.15407/nnn.15.04.0629 REFERENCES 1. F. A. Lindemann, Z. Phys., 14: 609 (1910). 2. M. Born, J. Chem.
