High temperature creep behaviour and microstructural changes of TAF 650 steel.
Original language description
The microstructure of W, Ni and Co containing high chromium martensitic steel TAF 650 was quantified by transmission electron microscopy and image analysis. Creep investigation of this steel reveals substantially longer time to fracture at lower stressesthan was expected from previous results. In order to find out microstructural features responsible for such improvement in the creep properties, microstructural investigations of TAF 650 steel after 18 700 hours creep exposure at temperature 650 C was performed. The results show that the synergetic effect of fine MX precipitates decreases due to Z-phase precipitation together with higher amount of Laves phase particles found in creep specimens compared to isothermally aged material is responsible for the creep strength. The prediction of creep behaviour based on a comparison of experimentally determined secondary phases and chemical composition with equilibrium values obtained by THERMO-Calc calculations are also provided.
