Сравнение воздействия ионной бомбардировки и механического ударного нагружения на аморфный сплав Fe72,5Cu1Nb2Mo1,5Si14B9

Abstract

The process of nucleation and growth of crystals in a metastable medium is studied theo-retically in the presence of Meirs kinetics. The removal of crystals and their “diffusion” in the space of radii are taken into account in the Fokker-Planck equation for the distribution func-tion. The time-dependent external heat (or mass) flux which controls the level of system met-astability is included in the heat (mass) balance equation. The effect of nonlinear growth rate for spherical crystals is shown.
