The Effect of Domain size in Polymorphic Activity in Soda-lime Glass under Extreme Conditions of Temperature, Strain Rate and Pressure
Abstract
Title:The Effect of Domain size in Polymorphic Activity in Soda-lime Glass under Extreme Conditions of Temperature, Strain Rate and PressureAbstract:Study the effect of domain size in polymorphic transformations by subjecting nano andmicro-pillars of soda-line glass, quartz, and sapphire of varying diameters (100 nm-2000 nm)and aspect ratios (1 to 2) to (a) axial shock compression using the existing Laser Spallation ShockFacility, and (b) ultrahigh pressures (>20 GPa) using a new setup that utilizes in-plane cylindrically focused laser-generated stress waves. These series of experiments will provide valuable experimental data for development of new models and also uncover if small domain size will result in the formation of high density polymorphs at significantly reduced pressure and temperature conditions.
