摘要：

We have generated 300-K isotherms to pressures as high as 300 GPa for Al, Cu, Ta, and W. Hugoniot data were reduced to isotherms using calculated thermal pressures. For these four metals, available experimental results permitted corrections of Hugoniot data for shock-induced strength as a function of shock pressure. High-pressure shock-wave data are extended to zero pressure using ultrasonically determined bulk moduli. For ease of evaluation of pressure-volume points, the isotherms are presented in the Vinet [J. Phys. C 19, L467 (1986)] form of the equation of state, along with isotherms for Mo and Au and Pt. (c) 2005 American Institute of Physics.
