Why tiny metal droplets take longer to solidify into glass: Fundamental observation in materials science NatureComms
as detailed in the following. A crystalline master alloy was prepared by melting the high-purity elements in a vacuum-sealed quartz tube at 1300 K. The alloy was remelted in a thin quartz tube under argon followed by water quenching, which resulted in the formation of glassy rod with 2 mm diameter and 60 mm length. The Pt-based MG nanofibers were prepared by thermoplastic press-and-pull technique.
The morphology of the sample was assessed by scanning electron microscopy performed directly on the FSC chips. We used a Hitachi TM3000 Tabletop Microscope for the Au-based samples and a Zeiss Sigma VP for the Pt-based samples. We determined the characteristic lengths of the Flash DSC specimens, in terms of the ratio between sample volume and free surface area. This metric is independent of the sample geometry and is the relevant parameter for the application of the FVHD model.
