“…[25], the authors find a characteristic scale length for short range order in similar V1 alloys to be 1.5-3 nm. A similar size (0.5-2 nm) was found for medium range order zones in Ti 60 Zr 15 Ni 15 Cu 10 amorphous alloy [26]. Furthermore, no change was observed in either the size or the density of the zone during hydrogenation, up to H/M ≈ 1.4.…”

“…Furthermore, no change was observed in either the size or the density of the zone during hydrogenation, up to H/M ≈ 1.4. This led to the conclusion that hydrogenation did not affect the structure of the material, and that it remained amorphous [26].…”

“…Such a behavior is very inviting for new applications, like micro-molding or micro-forming of components for MEMS/ NEMS devices [6][7][8]. However, together with other possible applications, metallic alloys with an amorphous structure have recently been proposed as candidate materials for permeation membranes for the purification of hydrogen [9][10][11][12][13][14]. Although these membranes generally operate in a range of temperature lower than the glass transition temperature, T g , their chemical and mechanical stability are important.…”

The high temperature mechanical properties of Zr50Ni27Nb18Co5 amorphous ribbons, proposed as metallic membrane material for hydrogen purification are presented. The mechanical behavior of the amorphous alloy, which generally does not exhibit a super-cooled liquid region, can be categorized into varying temperature regimes. A strain rate dependent phenomenon was observed between 425°C < T < 490°C in the strain rate range of 10 −6 s −1 to 10 −2 s −1 . However, the alloy did not exhibit Newtonian-flow characteristics at the varied test temperature and strain rate range employed in this study. Detailed analyses indicated that in these temperature regimes structural changes occur, resulting in the formation of nanocrystalline phases. The results from these mechanical tests corroborated with the microstructural changes that occurred at these temperatures/ strain rates.

“…Recently, the applications of BMGs have extended from magnetic to biomaterials applications by using the unique natures of BMGs such as high strength, high hardness and process flexibility in the supercooled region. [5][6][7][8] The Ni-based BMGs are one of the materials that exhibit high compressive strength of $2 GPa with a large glass forming ability (GFA) (many references can be found in 9) ). Extensive studies for Ni-based BMGs have been examined including selective materials members such as Ti, Zr, Sn and Nb, enabling fabrication of the 5 mm cylindrical bar (Ni 59 Zr 16 Ti 13 Nb 7 Si 3 Sn 2 ).…”

The Ni-based bulk metallic glasses (BMGs(Ni 59 Zr 16 Ti 13 Nb 7 Si 3 Sn 2 )) modified by Al, Hf and W have been synthesized for a specific application of penetrating materials. When Al was replaced with Zr of the Ni 59 Zr 16 Ti 13 Nb 7 Si 3 Sn 2 BMG, a large glass forming ability was observed, enabling to fabricate 7 mm cylindrical amorphous specimen. Also, when Hf or W was replaced with Ni of the Ni 59 Zr 16 Ti 13 Nb 7 Si 3 Sn 2 BMG, the 7 mm amorphous BMG specimen was obtained. For the Al modified BMG (Ni 59 Zr 15 Ti 13 Nb 7 Si 3 Sn 2 Al 1 ), a high strength of $2:6 GPa with $10% plastic strain was observed. It appears that the Hf modified BMG showed an excellent candidate for the application of penetrating materials among the examined BMGs.
