The failure was located on the welding HAZ region, parallel to the welding path. Branching cracks were detected at the edge of the rupture area. Deposits of corrosion products were also spotted. The optical microscope analysis showed the presence of transgranular failures which were related to the stress corrosion cracking (SCC) and were predominantly caused by the welding residual stress. The significant difference in hardness between the welded area and the pipe confirmed the findings. Moreover, the failure was also caused by the low Mo content in the stainless steel pipe which was detected by means of spark emission spectrometer. 2010-06-01T09:58:18Z 2010-06-01T09:58:18Z 2010-03-16 Article Praktische Metallographie/Practical Metallography, vol.47 (6), 2010, pages 206-215 0032-678X http://hdl.handle.net/123456789/8064 en Carl Hanser Verlag |
