Behavior of a magnesium alloy under high-speed strain under the action of a shock-wave load
Annotation
The article studies the motion of the rear free surface of a film sample of a magnesium alloy of submicron thickness under the action of subpicosecond laser pulses. Continuous diagnostics of the displacement of the free rear surface of the sample were carried out in the picosecond range in a single-pulse mode using spectral interferometry. The value of the spall strength at a strain rate of $\sim10^9$ s$^{-1}$, the value of which is about $53\%$ of the maximum possible strength for a magnesium alloy.
