## Description

- description: In this work, we combine two powerful small-scale testing methods,
    custom nanoindentation, and laser-driven microflyer (LDMF) shock, to measure the
    dynamic and spall strength of metals. The nanoindentation system is configured
    to test samples from quasistatic to dynamic strain-rate regimes. The LDMF shock
    system can test samples through impact loading, triggering spall failure. The
    model material used for testing is magnesium alloys, which are lightweight, possess
    high-specific strengths, and have historically been challenging to design and
    strengthen due to their mechanical anisotropy. We adopt two distinct microstructures,
    solutionized (no precipitates) and peak-aged (with precipitates) to demonstrate
    interesting upticks in strain-rate sensitivity and evolution of dynamic strength.
    At high shock-loading rates, we unravel an interesting paradigm where the spall
    strength vs. strain rate of these materials converges, but the failure mechanisms
    are markedly different. Peak aging, considered to be a standard method to strengthen
    metallic alloys, causes catastrophic failure, faring much worse than solutionized
    alloys.
