Nanoscale Structure, Dynamics, and Aging Behavior of Metallic Glass Thin Films

“…It is one of the few binary metallic alloys capable of glass formation in the bulk 29 . The glass forming region is expected to be between ~30–70 at.% hafnium for samples prepared via melting spinning (cooling rate ~10 3 –10 7 K/s) 30 . Here STM observations on Cu 100− x Hf x are presented.…”

“…29 The glass forming region is expected to be between ∼ 30 − 70 at.% hafnium for samples prepared via melting spinning (cooling rate ∼ 10 3 -10 7 K/s). 30 Here STM observations on Cu 100−x Hf x are presented. The surface is found to have hillock features with sizes dependent on Hf concentration, and pervasive dynamics manifested as hopping clusters.…”

Synthesis of amorphous alloys and amorphous-crystalline composites in the Cu-Nb-Hf system by ion beam mixing

“…3,4,[18][19][20] For instance, Qin et al 3 have reported that the Cu-Hf-Ti-Nb glassy alloys synthesized via rapid solidification could show a high glass-forming ability and high corrosion resistance, as well as improved mechanical properties. Jia et al 4 have synthesized glassy alloy rods with diameters of up to 10 mm in the Cu-Hf-Al system, and the alloys feature high strength and decent ductility.…”
