... surfaces were all similar in appearance, and a primary crack origin could not be identified. A secondary crack brought to fracture in the laboratory showed brittle, cleavage features rather than classic, tensile overload features. This suggested that the material was embrittled. Alkalies Caustic...

... extended radially from the electric resistant weld into the base metal. Metallographic examination revealed the cracks were transgranular and branching, characteristic of SCC in austenitic stainless steels. The fracture surfaces had a brittle cleavage-like appearance, typical of SCC in austenitic stainless...

... release of the load. Fracture was wholly of the brittle cleavage type except for a small crescent shaped lip at the top right-hand side. In this zone, fracture occurred at an angle of 45 deg to the general plane of fracture, indicative of failure in shear. Failure of the hook had taken place where...

.... The resultant cleaned surfaces revealed that the region of fast fracture consisted entirely of brittle cleavage failure. The initiation area was more heavily corroded but some cleavage facets could be distinguished in addition to a generally rather featureless fracture appearance. This suggests that both...
