Original abstract
Fatigue crack propagation behaviour in super duplex austenitic-ferritic stainless steel and its weld was analysed. ÄK-decreasing tests were performed and the fatigue crack growth rate (FCGR) data were generated. Fatigue crack closure was evaluated by processing the mechanical compliance data stored during the experiments. Fatigue crack branching was assessed based on the edge-filtering of high resolution light optical microscopy images. Although the comparison of the crack behaviour in the base material and the welded material was complicated by an irregular crack path within the welded specimen, distinctive differences of all evaluated characteristics were observed.
