Journal ArticleDOI
Structure and mechanical properties of compressed sodium aluminosilicate glasses: Role of non-bridging oxygens
Tobias Kjær Bechgaard,Ashutosh Goel,Randall E. Youngman,John C. Mauro,Sylwester J. Rzoska,Michal Bockowski,Lars Rosgaard Jensen,Morten Mattrup Smedskjær +7 more
TL;DR: In this paper, the authors examined changes in density, network structure, indentation hardness, and crack resistance of sodium aluminosilicate glasses with varying Al/Si ratio and thus non-bridging oxygen (NBO) content before and after 1 GPa isostatic compression at elevated temperature.
Journal ArticleDOI
Composition-Structure-Property Relations of Compressed Borosilicate Glasses
Mouritz Nolsøe Svenson,Tobias Kjær Bechgaard,Søren D. Fuglsang,Rune Hansen Pedersen,Anders Ø. Tjell,Martin Bonderup Østergaard,Randall E. Youngman,John C. Mauro,Sylwester J. Rzoska,Sylwester J. Rzoska,Michal Bockowski,Morten Mattrup Smedskjær +11 more
TL;DR: In this paper, the authors reveal a linear dependence of the plastic compressibility of borosilicate glasses on both initial trigonal boron content and relative change in hardness with pressure, with important implications for manufacturing tailored damage resistant glassy materials.
Journal ArticleDOI
Structure of MgO/CaO sodium aluminosilicate glasses: Raman spectroscopy study
Tobias Kjær Bechgaard,Garth Scannell,Liping Huang,Randall E. Youngman,John C. Mauro,Morten Mattrup Smedskjær +5 more
TL;DR: In this paper, the network structure of twenty quaternary MgO/CaO-Na2O-Al2O3-SiO2 glasses was analyzed using room temperature and in situ high-temperature Raman spectroscopy.
Journal ArticleDOI
Fragility and configurational heat capacity of calcium aluminosilicate glass-forming liquids
Tobias Kjær Bechgaard,John C. Mauro,Mathieu Bauchy,Yuanzheng Yue,Lisa Ann Lamberson,Lars Rosgaard Jensen,Morten Mattrup Smedskjær +6 more
TL;DR: In this article, a combined topological and thermodynamic approach was used to connect the configurational heat capacity (Cp,conf) with the liquid fragility (m) and glass transition temperature (Tg) of calcium aluminosilicate glass-forming liquids.
Journal ArticleDOI
Crucial effect of angular flexibility on the fracture toughness and nano-ductility of aluminosilicate glasses
Mengyi Wang,Bu Wang,Tobias Kjær Bechgaard,John C. Mauro,Sylwester J. Rzoska,Michal Bockowski,Morten Mattrup Smedskjær,Mathieu Bauchy +7 more
TL;DR: In this paper, the role of structure in controlling fracture toughness at fixed composition was investigated based on the experimental testing and atomistic simulations of a series of aluminosilicate glasses with varying thermal and pressure histories.
