Significant reduction in creep life of P91 steam pipe elbow caused by an aberrant microstructure after short-term service [PDF]
Scientific ReportsP91 steel is an important steam pipe for ultra-supercritical power plants due to its excellent creep strength, which generally has a design life of 100,000 h.

Low temperature friction stir welding of P91 steel
Defence Technology, 2016 Bead-on-plate friction stir welds were made on P91 alloy with low and high rotational speeds (100 and 1000 RPM) to study their effects on weld microstructural changes and impression creep behavior.

Creep Resistance and Microstructure Evolution in P23/P91 Welds. [PDF]
Materials (Basel)This paper summarizes the results of investigations into heterogeneous P23/P91 welds after long-term creep exposure at temperatures of 500, 550 and 600 °C. Two variants of welds were studied: In Weld A, the filler material corresponded to P91 steel, while in Weld B, the chemical composition of the consumable material matched P23 steel.

Influence of Creep Damage on the Fatigue Life of P91 Steel. [PDF]
Materials (Basel), 2022 The following paper presents the results of tests on samples made of P91 steel under the conditions of simultaneously occurring fatigue and creep at a temperature of 600 °C. The load program consisted of symmetrical fatigue cycles with tensile dwell times to introduce creep.
