dc.description.abstractAn analysis of the influence of heterogeneity of the ferriteaustenite welded joint on its integrity has been performed. The Charpy specimens, with notch positioned in different regions of welded joint, have been tested using the instrumented pendulum to separate crack initiation and growth energy. In all cases tested (different heat input, room and low temperature, down to -60°C), weld metal had the lowest toughness, due to the presence of S ferrite, which was not the case in the heat affected zones, having surprisingly high toughness, including both crack initiation and growth energies. Finally, J-R curves have been obtained by using standard fracture mechanics testing procedure and compared with crack driving forces, obtained numerically using King's method, enabling estimation of influence of cracks on integrity of ferriteaustenite welded joints in cylindrical pressure vessel.en
