摘要: The statistical and dynamic behaviors of the displacement-load curves a high-entropy alloy, Al0.5 CoCrCuFeNi, were analyzed for nanoindentation performed at two temperatures. Critical behavior serrations room temperature chaotic flows 200 °C detected. These results are attributed to interaction among large number slip bands. For temperature, recurrent partial events between bands introduce hierarchy length scales, leading critical state. °C, there is no spatial interference bands, which corresponding evolution separated trajectory behavior.
