High-resolution laser dilatometry applied to volume equilibration phenomena in a Zr-based bulk metallic glass Most models describing the glass transition are based on experimental or simulation data that were obtained from the supercooled liquid state, i.e., at temperatures above the glass transition. The slowing down of molecular or atomic motion occurring at the glass transition temperature Tg upon cooling complicates the access of kinetic processes with common measurement techniques at lower temperatures. However, possible changes around or below Tg regarding the structural dynamics are believed to yield key parameters in understanding the glass transition. |
