Characteristics of dislocation avalanches in the Al_0.1CoCrFeNi nanopillars. a shows the characteristic stress– and displacement–time curves for the in-situ compression experiment and for a [647]-oriented nanopillar. b plots the stress-binned complementary cumulative distribution, C(S, σ), of slip sizes as a function of the stress level over the maximum stress using 145 events from seven [647]-oriented samples of ~512–655 nm in diameters, compressed at a strain rate of 1 × 10⁻³/s and with similar load–displacement characteristic. c shows the scaling collapse of the same data as well as the predicted scaling function (see the text for details). d, e show two different types of displacement jumps. The velocity is calculated by the ratio of the displacement jump, S, and duration t. f Slip velocity as a function of shear stress. g Stress drop versus slip size. The avalanche velocities in (e) are averaged over a rolling slip size window of 2 nm, where the slip size distribution within the window is represented by the vertical bar, which marks the minimum and the maximum slip size
