Evidence of polyamorphic transitions during densified SiO glass annealing
Antoine Cornet, Christine Martinet, Valerie Martinez +1
In-situ X-ray scattering monitoring is carried out during temperature annealing on different densified SiO glasses. Density fluctuations and intermediate range coherence from x…
Relaxation processes of densified silica glass
Antoine Cornet, Valerie Martinez, Dominique de Ligny +2
Densified SiO2 glasses, obtained from different pressure and temperature routes have been annealed over a wide range of temperature far below the glass transition temperature (500$…
Permanently densified SiO glasses: a structural approach
Christine Martinet, Assia Kassir-Bodon, Thierry Deschamps +4
Densified silica can be obtained by different pressure and temperature paths and for different stress conditions, hydrostatic or including shear. The density is usually the macrosc…
Correlated evolution of structure and mechanical loss of a sputtered silica film
Massimo Granata, Elodie Coillet, Valérie Martinez +10
Energy dissipation in amorphous coatings severely affects high-precision optical and quantum transducers. In order to isolate the source of coating loss, we performed an extensive…
Density hardening plasticity and mechanical aging of silica glass under pressure: A Raman spectroscopic study
Damien Vandembroucq, Thierry Deschamps, Camille Coussa +4
In addition of a flow, plastic deformation of structural glasses (in particular amorphous silica) is characterized by a permanent densification. Raman spectroscopic estimators are…
Raman microspectroscopic characterization of amorphous silica plastic behavior
Antoine Perriot, Valérie Martinez, Laurent Grosvalet +4
Raman microspectroscopy was used to characterize amorphous silica plastic behavior. Using a correlation between Raman spectrum and density, a map of the local residual indentation-…
