Thermal-mechanical fatigue simulation of a P91 steel in a temperature range of 400–600°C [PDF]

, 2011
This paper deals with the identification of material constants to simulate the effect of cyclic mechanical loading and temperatures. A Chaboche viscoplasticity model was used in this study to model the thermal-mechanical behaviour of a P91 martensitic ...

Evaluation of Welded Joints in P91 Steel under Different Heat-Treatment Conditions

Metals, 2020
P91 steel has been of interest to many researchers over the past two decades. This interest is because this steel has very interesting characteristics for application in power plants, where it is common to have pipes that need to support steam at ...

Mechanical Characterization of Welded P91 Steel

Journal of Physics: Conference Series
Abstract The work presented in this study was performed to characterize the P91 base and weld metal by assessing the microstructure, tensile behaviour, hardness profile, creep behaviour and fracture morphology. Tensile test and short-term creep were performed on both the base and weld metal.

A Sunny Disposition and a Big Heart: Thematic Analysis of Parent‐Reported Socio‐Emotional Strengths in Dyslexia

Dyslexia, Volume 31, Issue 3, August 2025.
ABSTRACT Children with dyslexia have persistent and well‐characterised reading difficulties but may also have less well‐known socio‐emotional abilities. Socio‐emotional abilities in dyslexia could be leveraged in remediation efforts to improve outcomes, including resilience.

Enhancing Welding Productivity and Mitigation of Distortion in Dissimilar Welding of Ferritic-Martensitic Steel and Austenitic Stainless Steel Using Robotic A-TIG Welding Process

Journal of Manufacturing and Materials Processing
The P91 martensitic steel and 304L austenitic stainless steels are two mainly used structural steels in power plants. The major problem in conventional multipass tungsten inert gas (TIG) welding of P91/304L steel is high heat input and joint distortion ...

Creep Crack Growth Behavior of a P91 Steel Weld

Procedia Engineering, 2014
AbstractModified 9Cr-1Mo steel (P91) weld joints operating at elevated temperatures are well known to be prone to premature failure due to cracking in the heat affected zone because of the gradients in microstructure, popularly referred to as Type IV cracking.

Exploring the Role of Microglial Cells in the Gut–Brain Axis Communication: A Systematic Review

Journal of Neurochemistry, Volume 169, Issue 7, July 2025.
Gut microbiota composition influences brain health through the gut–brain axis by modulating microglial activation states. A balanced microbiota promotes the production of beneficial metabolites like short‐chain fatty acids (SCFAs), which maintain gut barrier integrity and support anti‐inflammatory surveillance microglia, contributing to neuroprotection

A Meta‐Analysis of the Effects of Early Life Stress on the Prefrontal Cortex Transcriptome Reveals Long‐Term Downregulation of Myelin‐Related Gene Expression

Brain and Behavior, Volume 15, Issue 6, June 2025.
To elucidate the long‐term effects of early life stress (ELS) on the prefrontal cortex (PFC), we conducted a meta‐analysis of five publicly available transcriptional profiling datasets from adult rodents that had experienced ELS. We observed consistent downregulation of myelin‐related genes following ELS and upregulation related to major depressive ...

Material Challenges and Alloy Selection for Particle/s‐CO2 Heat Exchangers in Concentrated Solar Power Systems

Advanced Engineering Materials, Volume 27, Issue 10, May 2025.
Combining supercritical CO2 (s‐CO2) cycles with particle‐based heat transfer media holds great potential in concentrated solar power plants but poses enormous material challenges. The particle/s‐CO2 heat exchanger must withstand extreme conditions, including high temperatures, pressures, CO2 corrosion, and erosion.
