Creep behavior and microstructural stability of P23/P91 dissimilar welds during creep at 550°C
Original language description
The paper deals with the study on creep behavior and minor phase evolution in two types of heterogeneous weld joints of P23 and P91 steels during long-term creep exposure at 550 °C. The filler material in Weld A corresponded to P91 steel and the filler metal in Weld B was similar to the chemical composition of P23 steel. The creep rupture tests on the cross-weld test pieces of both welds revealed that most failures occurred in the partly decarburized zones of P23 steel or WM23. The carbon redistributionand the minor phase evolution across the sharp P23/P91 interface were calculated using Thermocalc and Dictra computer packages. The experimental study on minor phase evolution using both EDX and SAED in TEM was in a good agreement with the computer simulations, except for M23C6 phase in P23 (WM23) steel. EBSD technique used to study on microstructure changes along the P23/P91 boundary confirmed the slowing down of the recovery/recrystallization processes in the partly decarburized zone
