  Amorphous metallic foams are prospective materials due to unique combination
of their mechanical and energy-absorption properties. In the present work,
atomistic dynamics simulations are performed under isobaric conditions with the
pressure $p = 1.0$ atm in order to study how cooling with extremely high rates
($5\times10^{13}$--$5\times10^{14}$ K/s) affects the formation of pores in
amorphous titanium nickelide. For equilibrium liquid phase, vaporization
temperature $T_{b}$ and the equation of states in the form of $\rho(T)$ are
determined. It is found that the porosity of this amorphous solid does not
depend on cooling at such high rates, whereas the pore morphology depends on
the magnitude of the cooling rate. The obtained results will be in demand in
study of mechanical properties of amorphous metallic foams with a nanoporous
structure.
