Morphology of Creep Fracture of a Phase‐Separated Borosilicate Glass

A phase‐separated borosilicate glass with interconnected microstructure was stretched in the viscoelastic temperature range. When elongated, significant necking and subsequent fracture occurred. SEM study of the fractured samples revealed an enormous amount of crazing on the surface and void formation in the bulk of the samples near the fractured edges. Copyright © 1980, Wiley Blackwell.
