Oxidation of Zr-based metallic glasses and nanocrystalline alloys
Autor: Uwe Köster, Lioba Jastrow
Publikováno v: Materials Science and Engineering: A. :57-62
Oxidation kinetics of bulk Zr-based metallic glasses seems to be controlled by oxygen diffusion through the scale towards the ZrO 2 /glass interface. Two modes of oxidation were observed: depending on the alloy either: (1) relative slow growth of hom

Oxidation of Cu60Zr30Ti10 metallic glasses
Autor: Lioba Jastrow, Uwe Köster, Monika Meuris
Publikováno v: Materials Science and Engineering: A. :165-168
Cu–Zr-based bulk metallic glasses are of increasing interest due to their excellent properties. Cu-rich Cu 60 Zr 30 Ti 10 and Zr-rich Zr 69.5 Cu 12 Ni 11 Al 7.5 glasses (numbers indicate at.%) are examples which combine good glass forming ability w

Catastrophic oxidation of Zr-TM (noble metals) glasses
Autor: Lioba Jastrow, Uwe Köster, Monika Meuris
Publikováno v: Materials Science and Engineering: A. :440-443
Glassy Zr 70 Pd 30 as well as Zr 70 Au 30 prepared by melt-spinning exhibit a “catastrophic” oxidation behavior in wet as well as synthetic air. For example, at a temperature of 270 °C, ribbons (about 30 μm in thickness) are fully oxidized with

Influence of alloying on the formation of Zr-based quasicrystals
Autor: L. Lyubenova, Lioba Jastrow, Uwe Köster, Varsha Khare, Rainer Janlewing, Daniela Zander
Publikováno v: Journal of Non-Crystalline Solids. :23-28
Glassy Zr–Cu–Ni–Al precursor alloys exhibit quasicrystal forming ability in a narrow concentration range via isothermal heating. The formation of quasicrystals has been explained by various arguments. Often, they are considered as Hume-Rothery

Absorption/desorption behavior of hydrogen and deuterium in a Pd-coated Zr-based amorphous alloy
Autor: E. Tal-Gutelmacher, Daniela Zander, Uwe Köster, Dan Eliezer, Lioba Jastrow, Noam Eliaz
Publikováno v: Materials Science and Engineering: A. 358:219-225
Palladium (Pd) coating was found to enhance significantly the absorption/desorption behavior of hydrogen in amorphous Zr69.5Cu12Ni11Al7.5, thereby improving the applicability of this alloy to hydrogen storage systems. This paper demonstrates the diff

Hydrogenation of Pd-coated Zr–Cu–Ni–Al metallic glasses and quasicrystals
Autor: Lioba Jastrow, E. Tal-Gutelmacher, D. Eliezer, Uwe Köster, D. Zander
Publikováno v: Journal of Alloys and Compounds. :654-657
Zr-based metallic glasses and quasicrystals might be excellent materials for hydrogen storage because of their high number of tetrahedrally coordinated sites suitable for interstitial hydrogen and their favorable hydrogen chemistry. However, hydrogen
