dc.description.abstractIn this study, an assessment of crack propagation mode in martensitic stainless steels heat affected zone was carried out with electron back scatter diffraction (EBSD) with focus on the effect of environmental variables. Girth welded samples were subjected to four point bend tests in sour and sweet environments. Scanning electron microscope and electron back scatter diffraction technique were both used to study the crack propagation mode and interaction of crack tip with microstructures. Study showed that sample tested in sour environment failed with transgranular cracking and samples tested in sweet environment failed with intergranular stress corrosion cracking mode. The proposed mechanism for the failure was sulphide stress corrosion cracking and intergranular precipitation of carbide by sensitisation process respectively. The correlation between crack path and grains misorientation was studied with aid of EBSD technique.en_US
