Finite element thermal analysis of the fusion welding of a P92 steel pipe [PDF]
Mechanical Sciences, 2012 Fusion welding is common in steel pipeline construction in fossil-fuel power generation plants. Steel pipes in service carry steam at high temperature and pressure, undergoing creep during years of service; their integrity is critical for the safe ...

GAMM-Mitteilungen, Volume 44, Issue 1, March 2021., 2021 Abstract Currently, the growth of material data from experiments and simulations is expanding beyond processable amounts. This makes the development of new data‐driven methods for the discovery of patterns among multiple lengthscales and time‐scales and structure‐property relationships essential.

Creep Deformation and Rupture Behaviour of P92 Steel at 923 K
Procedia Engineering, 2013 AbstractCreep deformation and rupture behaviour of P92 steel has been examined at 923K for stresses ranging from 75 to 150MPa. The steel exhibited well defined primary, secondary characterized by minimum creep rate and prolonged tertiary creep stages.

Bond Behavior between Concrete and Self‐Expansion Polymer Material under Normal Pressures
Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 Self‐expansion polymer grouting technology is a new rapid trenchless method for repairing leakage and subsidence of underground concrete structures. The bond between polymer and concrete is critical to determine the ultimate conditions of repaired concrete.

Influence of thermal ageing on creep rupture mechanism and creep life of P92 ferritic steel
Materials Research Express, 2020 In order to analyze the effect of thermal ageing on creep rupture mechanism and establish a method for predicting the creep rupture life of P92 heat-resistant steel under thermal ageing, creep tests were performed on P92 steel specimens, aged at 650 °C ...

Origin of Threshold Stresses in a P92-type Steel
Transactions of the Indian Institute of Metals, 2015 The creep behavior of a P92-type steel was examined at 923 K. The threshold shear stress of 51 MPa was revealed by an analysis of steady state creep behavior at applied stress ranging from 118 to 200 MPa. The tempered martensite lath structure stabilized by M23C6-type carbide particles with an average size of about 110 nm and MX-type carbonitrides with
