| 中文摘要 | An increasing tendency of serrated flow with increasing loading rate of a La-based (La) metallic glass (MG) with pronounced Johari-Goldstein relaxation in nanoindentation is investigated, which is abnormal compared to precedent observations where the serrated flow normally decays with increasing loading rate as discovered in the referenced Zr-based (Zr) and Pd-based (Pd) MGs. Based on systematic analysis, a unified dimensionless number is proposed to elucidate the different origins of the abnormal serrated flow of the La MG and the normal serrated flow of the Zr and Pd MGs. The abnormal serrated flow behavior of the La MG provides critical implications in understanding the role of Johari-Goldstein relaxation in the flow of metallic glasses. (C) 2016 Elsevier B.V.
