dc.description.abstract	© 2016 The Author(s).The redistribution of heat between two subsystems in the two-dimensional crystal consisting of particles interacting by means of the Lennard-Jones potential with argon parameters is considered in the frame of molecular dynamics method. Calculations of heat flux, its time derivative and kinetic temperature gradient showed that the characteristic relaxation times of the nonequilibrium flux within the nonlocal Cattaneo model at temperatures 10. K. <. T<. 40. K are very small (τv<10-11s) and, comparable with the time of phonons free path.
