Metallic glasses (MGs) are becoming increasingly attractive due to their outstanding mechanical properties. Although MGs have been studied for the last couple of decades, development has mostly followed empirical glass-forming rules.
Density functional theory (DFT) calculations have been performed on various metallic glasses (3 binary, 1 ternary and 1 multicomponent) to determine their density and elastic properties. To allow for comparison with these calculations, combinatorial magnetron sputtering was used to produce thin film MGs. Mechanical properties were determined by nanoindentation and in-situ scanning electron microscopy (SEM) fracture testing of microscale cantilevers, which were produced by focused ion beam (FIB) milling. Further microstructural characterization has progressed via synchrotron diffraction, transmission electron microscopy (TEM) and atom probe tomography (APT). The combination of theoretical (ab initio molecular dynamics) and experimental (mechanical and microstructural characterization) approaches allows for a deeper understanding of the underlying structure-property relationships within these metallic glasses.
