Popis:	The study is aimed at the establishment of regions of stable (monotonic) and unstable (jumpwise) plastic flow in bulk amorphous Zr46.8Ti8Cu7.5Ni10Be27.5 alloy under the conditions of local deformation. The characteristics of the jumpwise plastic flow in bulk amorphous Zr46.8Ti8Cu7.5Ni10Be27.5 alloy are studied by the method of continuous nanoindentation (depth-sensing testing) in the range of strain rates $$\dot \varepsilon $$ from 10−2 to 104 s−1. The boundaries between the regions of homogeneous and localized plastic strain are established and the fractions of monotonic and jumpwise plastic strain under the indenter are determined.
