  • Shock loading of materials alters the microstructure and considerably degrades mechanical performance. Here, shock loading of a nanocrystalline Cu–Ta alloy is found to induce minor changes to microstructure and mechanical performance, attributed to the annihilation of defects during deformation.

  • Ballistic transport of dislocations and the resulting phonon drag are known to occur in crystalline metals under high strain rates, causing embrittlement. Here, we leverage dislocation confinement at the nanometer scale to entirely suppress the phonon drag regime, even at strain rates as high as 109 s−1.
