Change of quasilattice constant during amorphous-to-quasicrystalline phase transformation in Zr65Al7.5Ni10Cu7.5Ag10 meta...
The amorphous-to-quasicrystalline phase transformation in a Zr65Al7.5Ni10Cu7.5Ag10 metallic glass has been investigated by monitoring the quasilattice constant and the composition of quasicrystalline particles in the samples annealed in vacuum at 663 K for various times. It is found that the quasilattice constant decreases with annealing time and s...
Modelling of Zr-O and U-Zr-O melts oxidation and new crucible tests
This report summarises the results of task WP7.2 of the European COLOSS Project conducted within the 5"t"h Framework Programme on ''Nuclear Fission Safety''. The objective of this multi-partner task is the development of models regarding the oxidation of U-O-Zr mixtures, in particular: Models that can adequately simulate the oxidation of U-O-Zr mix...

Evidence of polymorphous amorphous-to-quasicrystalline phase transformation in Zr66.7Pd33.3 metallic glass
The amorphous-to-quasicrystalline phase transformation and the pressure effect on the transformation in a Zr66.7Pd33.3 metallic glass have been investigated by in situ x-ray diffraction measurements using synchrotron radiation. It is found that the transformation is a polymorphous reaction and external pressure enhances the onset temperature for th...

The solubility of rhodochrosite (MnCO3) and siderite (FeCO3) in anaerobic aquatic environments
Natural groundwaters are often reported to be highly supersaturated with the carbonate minerals siderite (FeCO3) and rhodochrosite (MnCO3). The kinetics of precipitation and dissolution were determined in the light of new determinations of the solubility products of siderite and rhodochrosite. Laboratory experiments showed that the precipitation ki...
