In Situ SEM/EBSD analysis of fatigue crack propagation behavior of a super duplex stainless steel
Original language description
Fatigue crack branching and deflection behaviour in an UNS S32750 (SAF 2507) duplex stainless steel has been investigated using an In-situ SEM/EBSD fatigue test and a conventional da/dN methodology. Occurrence of crack branching results mainly from the extrusions and intrusions of slip bands developed in the grains. The number of crack branches formed depends strongly on the loading condition and the microstructure of the material. The in-situ observation confirms that the formation of crack branches can significantly reduce the crack propagation rate that leads to crack growth retardation in the main mode I crack path. The crack branches formed are usually not ideal. They can propagate almost transversely to the main crack direction with a mode II stress intensity factor, SIF, and a rate that is much higher than that of the main crack. Crack deflection occurs mainly at the phase boundaries. A high crack deflection can also lead to a crack growth retardation. The high crack deflection
