摘要
The results of nanoindentation tests of bulk glassy Pd40CU30Ni10P20 using a specially designed instrument with high time and spatial resolution are presented. Pronounced serrations of the indenter penetration depth are observed. The parameters of serrated flow (the number of serrations, their amplitude and duration) are dependent on the duration of the loading force pulse. (C) 2001 Acta Materialia Inc.
