文摘
- •
We studied a sodium borosilicate glass quenched from different volumes.
- •
The different structures were submitted to a series of displacement cascades.
- •
Constraining the volume causes a more homogeneous density distribution.
- •
Areas rich in sodium are more compressible.
- •
A constrained glass swells during the accumulation of displacement cascades.
