Published: 01 January 2002
Fig. 16 Cross section through leak in steam-generator wall. Crack extends across weld metal, base metal, and HAZ. Erosion obliterated much of the original crack detail. More

Fig. 17 Fracture morphology of steam-generator wall in a region where regularly spaced striations typical of fatigue are evident. More
Image
Published: 01 January 2002
Fig. 18 Fracture surface of a failed steam-generator sample. The fracture morphology is characteristic of fatigue cracking, but 1 ppm of Ce − under constant extension rate testing produced this same fracture morphology in laboratory tests. The initiation site is on the inside surface More
