Interactions of stress corrosion cracks in cold drawn pearlitic steel wires: An X-ray micro-computed tomography study

X-ray micro-computed tomography (micro-CT) was used for analysis of stress corrosion cracking (SCC) of cold drawn pearlitic steel wires from a cable bolt from an underground coal mine. The results were compared to those obtained from magnetic particle inspection (MPI) of the wire surface and optical microscopy (OM) and scanning electron microscopy (SEM) examination of sections through the wires. The high-resolution two-dimensional (2D) OM and...
