Shock compression of porous aluminum and nickel at megabar pressures

Data are given on shock compression of porous samples of aluminum with the initial density $\rho_{00}=0.34$ g/cm$^3$ and nickel with $\rho_0=0.44$ and $0.32$ g/cm$^3$. In the case of aluminum, all results are obtained for the first time ever. The range of pressure being investigated is from $0.25$ to $76$ GPa. For nickel, a shock adiabat is found with the porosity $m=\rho_0/\rho_{00}=28$ (which is the highest porosity for metals) and an adiabat with $m=20$ at a pressure of $92$ GPa, which is approximately twice the respective values obtained previously. Comparison is made with the results of other researchers.
