Cm - Micrography by OMDf - Close to the External Surface
Micrography of a longitudinal section of the bolt at the fracture surface. The material showed several creep voids and interconnected cracks. The broken bolt remained in service during some time and the fracture surface presented a thick oxide layer(grey). As polished.
