  Some results of computer simulation of atomic structure of amorphous metals (Al, Cu, Ni), received from melts by force of ultra-fast cooling are cited and analyzed from the position of dynamic systems theory. It is determined that the atomic structure of such amorphous metals is unpredictable and irreproducible. A
homologous equation for a structural instability research is received. Found aluminum amorphous state with a low degree of short range order.
