Structure of crystalline and amorphous solid bodies on the Lennard-Jons systems

The processes of crystallization and glass transition of Lennard-Jones systems are investigated depending on the cooling rate from the gaseous phase to temperatures below 2/3 of the crystallization point. Simulated is the cooling of the system at speeds of 108, 109, 1010 and 1011 K/s at pressures of 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5 and 4.0 MPa. It is shown that the structure of crystalline solids obtained in the cooling process depends not only on the rate of temperature change, but also on the pressure in the particle system. At higher pressure, a more ordered crystal lattice is formed. High cooling rates at low pressures make it possible to obtain the structure of glassy solid bodies, which is reflected in their functions of the particles radial distribution.
