Electrical Resistivity of Aluminum under Shock Compression

Abstract
Electrical resistance measurements of aluminum foil are conducted under shock compression using the electric contact technique. Shock wave pressure p dependences of the electrical resistance R and the resistivity ρ are obtained for pressure range up to 22 GPa. The found dependence R(p) is a monotonically increasing smooth function of the pressure. The dependence ρ(p) is more complex: with increasing pressure, the electrical resistivity first decreases and then increases.
