Micropillars with diameters of 3.8, 1 and 0.7 μm were fabricated from a two-phase Zr-based metallic glass using focus ion beam (FIB), and then tested in compression at strain rates from 1 × 10-4 to 1 × 10-2 s-1. The apparent yield strength of the micropillars ranges from 1992 to 2972 MPa, or 25-86% increase over that of the bulk specimens. This strength increase can be rationalized by the Weibull statistics for brittle materials.
