Title: | Slip avalanche in nanoscratching of metallic glasses | Authors: | Han, DX Wang, G Ren, JL Song, SX Li, J Yi, J Jia, YD Xu, H Chan, KC Liaw, PK |
Issue Date: | 2017 | Source: | Journal of applied physics, 2017, v. 122, no. 11, 115108, p. 115108-1-115108-7 | Abstract: | Slip avalanches, similar to discrete earthquake events, of Zr-, Co-, and Ce-based metallic glasses during nanoscratching were investigated. Differing from the conventional continuum approach, mean-field theory, which is an inherently-discrete model, was applied to analytically compute intermittent slip avalanches. Mean-field theory was first connected with the potential energy barrier and concentration of free volume in order to study the stick-slip behavior. The results suggest that the motion behavior of free volume affects the critical slip avalanche size.
