Inelastic scattering and its contribution to the investigation of glass structure are discussed in Sect. 7.2 . Diffraction and scattering techniques are available for experimental study of structure; Raman scattering allows in addition non-destructive analysis; Brillouin light scattering of light is a ...
On the other hand, the Wendt-Abraham parameters are calculated to determine the glass transition temperature ( T g ), which depends strongly on the cooling rate; it increases while the cooling rate increases. On the basis of CN analysis and Voronoi tessellation, we demonstrate that the ...
Amorphous solids such as glass, plastics and amorphous thin films are ubiquitous in our daily life and have broad applications ranging from telecommunications to electronics and solar cells1–4. However, owing to the lack of long-range order, the three-d
This bonding scenario world be expected to give rise to a dense structure with increased rigidity, consistent with the remarkably high T-g values reported in the literature for these glasses. 展开 会议名称: Annual Conference of the Society-of-Glass-Technology ...
The structure ofAl88Y7Fe5metallic glass has been investigated by differential scanning calorimetry, x-ray powder diffraction, and x-ray absorption fine structure (XAFS) techniques. The amorphous alloy crystallizes according to the following scheme:amorphous→α‐Al+residual amorphous→α‐Al+Al3Y+Al...

one can identify the dilatometric transition temperature and glass transition temperature. The QNb alloy has a dilatometric transition temperature of approximately 458 K in the as-cast state. After relaxing the structure by heating close to{T}_{{{\rm{g}}}the dilatometric transition temperature...
A complete structural study has been carried out on sodium borophosphate glass containing increasing amounts of either niobium or tantalum. A combination of high energy x-ray diffraction, neutron diffraction, extended x-ray absorption fine structure, nuclear magnetic resonance, and infrared and Raman ...

The relation between the fragility of glass-forming systems, a parameter which describes many of their key physical characteristics, and atomic scale structure is investigated by using neutron diffraction to measure the topological and chemical ordering for germania, or GeO(2), which is an archetypal...
