Effect of pressure quenching on the structures and properties of borosilicate glasses: Insights from molecular dynamics simulations (open access)

Effect of pressure quenching on the structures and properties of borosilicate glasses: Insights from molecular dynamics simulations

Article describes how processes including hot compression, cold compression and subsequent annealing on the structures and properties are investigated and compared. They found that applying pressure up to 10 GPa at the glass transition temperature led to permanent densifications and a dramatic increase of elastic moduli by 90%, while thermal annealing reversed the increase and applying pressure at ambient temperature did not increase the modulus.
