| Abstract Scope |
Metallic glasses have drawn a lot of attention since their first observation due to attractive properties like high strength, fracture toughness and corrosion resistance. In most cases, metallic glasses are used as-is without any further processing, to retain their fully amorphous state, unlike most crystalline materials. Recently, it has been shown that the mechanical properties of metallic glasses can be tuned via annealing at certain fictive temperature, setting the structure into that of supercooled liquid at the fictive temperature. We aim to see how the process can affect metallic glasses with same composition but different initial structure. We’ve found that for metallic glasses with LDPR, mechanical properties can vary significantly with cooling rate. After annealing at the same fictive temperature, we investigated the deformation behavior of metallic glasses fabricated from different cooling rates utilizing nanoindentation experiments. We expect this research to give new insights into post-processing methods of metallic glasses. |
