Abstract

The shock compression of magnesium (Mg-4Al-2Zn) alloy polycrystalline films on glass under ultrashort loads driven by sub-picosecond laser pulses was investigated. The continuous diagnostics of motion and reflectivity changes of the free rear surface of the samples was carried out in the picosecond range (≤200 ps) in a single pulse mode using ultrafast spectral interferometry. We present the data on elastoplastic shock wave evolution at a propagation distance of several hundreds of nanometers, elastic precursor decay, shear, and tensile strengths at the extreme strain rate of ∼109 s−1.
