Description:

(abstract)

Nanoindentation-induced deformation in Zr-based bulk metallic glasses in distinct structural states was studied over a broad temperature range, both below and above the glass transition temperature. These findings emphasize the occurrence of a predominant deformation mechanism, identified as a percolation or diffusion process, triggered by exceeding a chemical and topological short-range order-insensitive energy barrier.
