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.

Experimental and Numerical Analysis of Initial Plasticity in P91 Steel Small Punch Creep Samples. [PDF]
Exp Mech, 2017 To date, the complex behaviour of small punch creep test (SPCT) specimens has not been completely understood, making the test hard to numerically model and the data difficult to interpret.

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.

DEFORMATION-MECHANISM-BASED MODELING OF CREEP BEHAVIOR OF P91 STEEL
Jixie qiangdu, 2022 Creep behavior of P91 steel was studied by using a constitutive model based on deformation mechanism. Combined with the experimental data, it was found that the minimum creep rate has an obvious exponential relationship with the applied stress during ...

Morphology of Inclusions and Its Refinement Mechanism in the New P91 Heat-Resistant Pipeline Steel
Metals, 2022 A new type of P91 heat-resistant pipeline steel ingot was prepared by feeding Al twisted wire into a steel melt through a multi-point regional micro-supply method, combined with electromagnetic stirring. The type, shape, and size of inclusions in the new

Temperature-Dependent Fatigue Characteristics of P91 Steel [PDF]
Acta Mechanica et Automatica, 2020 Abstract In this paper, the experimental investigations, constitutive description and numerical modelling of low-cycle fatigue behaviour of P91 steel in non-isothermal conditions are presented. First, experimental tests are performed to recognise different aspects of material behaviour.

Creep Rate, Friction, and Wear of Two Heat-Affected Zone Regions of 9–12 wt.% Cr Steels
Metals, 2021 Coarsening of precipitates can have a profound effect on the mechanical properties of martensitic 9–12 wt.% Cr steels, which are typically used in critical parts of fossil-fuel power plants such as turbines, headers, and main steam pipes.
