Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 10 <sup>5</sup> s <sup>−1</sup>
, remarkably revealing a hardness upturn in all three materials. Further, post-deformation analysis of single-crystalline molybdenum revealed that the hardness upturn was primarily driven by increased dislocation density, with phonon drag-traditionally considered a dominant contributor playing a minimal role.
