    Hugoniot adiabats and isoentropic unloading curves for Ni and Al and their ordered NiAl and Ni3Al alloys are calculated within the framework of a method based on the electron-density functional theory. The residual temperature and volume of a completely unloaded material are determined under various initial states on the Hugoniot adiabat. The results of calculation of the adiabats for pure metals are in conflict with known experimental data by no more than 15%. It is s shown that the thermodynamic parameters which characterize the alloys considered under the conditions of a shock-wave experiment are close to the corresponding values for pure Ni and are not the lumped averages of the corresponding characteristics of pure metals.
