Transition in deformation mechanism of aluminosilicate glass at high pressure and room temperature

Deformation experiments for 20(MgO or Na2O)‐20Al2O3‐60SiO2 glasses were performed in simple shear geometry at 1.5‐5 GPa and room temperature. An abrupt change in the thinning rate and the turning of the birefringence azimuth at a shear strain of γ = 1‐2 indicate a transition of deformation mechanism...
