Amorphous metallic foams are prospective materials due to unique combinationof their mechanical and energy-absorption properties. In the present work,atomistic dynamics simulations are performed under isobaric conditions with thepressure $p = 1.0$ atm in order to study how cooling with extremely high rates($5\times10^{13}$--$5\times10^{14}$ K/s) affects the formation of pores inamorphous titanium nickelide. For equilibrium liquid phase, vaporizationtemperature $T_{b}$ and the equation of states in the form of $\rho(T)$ aredetermined. It is found that the porosity of this amorphous solid does notdepend on cooling at such high rates, whereas the pore morphology depends onthe magnitude of the cooling rate. The obtained results will be in demand instudy of mechanical properties of amorphous metallic foams with a nanoporousstructure.
