Abstract

A Zr-based bulk metallic glass (BMG) was investigated to using dynamic modulus mapping (DMM) to explore spatial variations of mechanical properties. Elastic modulus patterns were determined using storage modulus maps at different positions on the sample. We partially re-confirmed the existence of a heterogenous directionally aligned elastic microstructure network in a Zr-based BMG. A K-means clustering algorithm was applied to the appropriate modulus maps, to divide the data into stiff, intermediate and compliant regions, however data on several of the maps was inconclusive.
