Expansion of shock-compressed zinc in isentropic release waves is investigated experimentally over the range of pressures from P ≃100 to 0.1 GPa and densities from ρ≃ 1.2ρ0 to ∼ 0.01ρ0, where ρ0 is the normal density of the metal. Obtained data are analyzed with the use of a multiphase equation of state, which takes into account melting and evaporation effects at high temperatures and pressures.
