## Description

- description: CoCrNi and CoCrNiSi0.3 nanopillars exhibited distinct deformation behaviors
    under in-situ compression experiments with a strain rate of 2×10-3 s-1 in a transmission
    electron microscope. The former was mainly deformed through slip-dislocations
    and the formation of slip-bands with edges extending to the nanopillar’s boundaries;
    in contrast, the latter was primarily deformed by twinning and partitioned by
    deformation nanotwins, with different variants intersecting each other to form
    closed nano-blocks. Si addition not only enhanced the solid solution strengthening
    effect but also facilitated the formation of nanotwins, resulting in a delayed
    first strain burst in the CoCrNiSi0.3 nanopillar at a strain of 9.6 % with strength
    39 % higher than that in CoCrNi at a strain of 7.1 % during the in-situ deformation.
    In addition, closed nano-blocks effectively strengthened the CoCrNiSi0.3 nanopillar,
    which possessed strength 24 % higher than that of the CoCrNi nanopillar at the
    same strain of about 20 %.
