Popis:	It is shown that a sharp increase in viscosity, a change in the decay rate of correlations, and the appearance of nonequilibrium and transverse sound in a thin film of aluminum melt during rapid cooling occur in the same temperature range. The analysis is performed using the shear stress autocorrelation functions calculated by the molecular dynamics method. The cooling rate dependences indicate the transition of the metastable state into the amorphous one rather than a phase transition.
