    in nanoindented tungsten

## Description

- description: As refractory metals are increasingly subjected to extreme service
    conditions, a comprehensive understanding of their fundamental deformation mechanisms
    has become indispensable, particularly considering the persistent discrepancies
    between predicted and experimentally observed behavior under complex stress fields.
    Therefore, nanoindentation on the principal crystallographic planes of pure tungsten
    single-crystals was performed and revealed a strong influence of crystal orientation
    on indent appearance, hardness and incipient plasticity. For the (100) surface
    we observe a confined plastic zone with pronounced pile-up and highest hardness
    of 5.18 ± 0.07 GPa among the three orientations. Unusually long streaks of dislocations
    form on the surface of (110)-oriented samples demonstrating tungsten's non-Schmid
    behavior. The (111) surface exhibits hitherto unreported appearance of slip and
    highest pop-in loads.
