Caloric equations of state of structural materials

Two versions of Mie‐Gruneisen‐type caloric equation of state (EOS) model are proposed. Constructed are EOS for about 150 structural materials (metals, alloys, rocks, minerals, polymers, composites, and other materials). The carried out comparison of the calculated by EOS thermodynamic properties with numerous high‐pressure data testified their reliable description. The presence of correct theoretical asymptotes guarantees the reliable thermodynamic description in the phase diagram regions unaccessible to experimental test. These allow a wide use of the EOS in carrying out computer simulation.

Wide‐range multi‐phase equation of state of metals

To describe states of the greatest practical interest for physics of high energy densities of model of thermodynamically complete equation of state (EOS) is proposed. The EOS accounts for high‐temperature melting, evaporation, and ionization effects and allows to calculate thermodynamic properties of metals in solid, liquid, and plasma states as well as in two‐phase solid‐liquid and liquid‐gas regions. The comparison with static and dynamic high‐pressure data is presented.

Equations of state for metals at high energy densities

The semiempirical quasiharmonical equation of state (EOS) model is constructed to describe the thermodynamical properties of metals in a broad region of parameters: 0.03≤ρ/ρ0≤100; 0<T<106 K. The model accounts for cold curve (T=0 K) part, thermal unharmonic vibrations of nuclears, and thermal excitations of electrons. The EOS are constructed for twenty seven metals. The presented results are compared with available experimental data obtained in statical and dynamical experiments.

Investigations of metals in the liquid and plasma states by use of shock waves

Abstract The use of shock-wave techniques gives unique possibilities to investigate liquid metals properties over a range of the phase diagram extending from the solid state to the vapour phase of liquid metals properties, which were obtained by such methods. Generalization of shock-waves data on the base of wide-range equation of state is also presented.

OPTICAL PROPERTIES OF DENSE PLASMA IN SHOCK AND RAREFACTION WAVES

Results of the experiments on measurements of optical properties of strongly coupled hot plasmas are presented. The fast optical pyrometry enabled us to obtain information on the thermodynamic and optical properties of condensed matter in the supercritical region of parameters and in the vicinity of the saturation curve. The experimental information is compared with the wide-range semiempirical equation of states and optical models of plasma.
