Effect of temperature on fatigue crack growth in P92 steel
Metals and Materials International, 2003Fracture at high temperature has become a critical problem for such high temperature components as those used in power plants or oil refinery plants, because both high operating temperature and pressure are required for better thermal efficiency. Therefore, it is very important to approach such problems from the viewpoint of high temperature material ...

Investigation of Creep Damage and Cavitation Mechanisms in P92 Steels
Advances in Materials Technology for Power Plants, 2013Abstract Contrary to expectations, long-term performance of creep stress enhanced ferritic steels (CSEF) falls short of predictions based on short-term data. This discrepancy is attributed to the formation and growth of creep voids, leading to reduced ductility.

Creep deformation and rupture behaviour of thermal aged P92 steel
Materials at High Temperatures, 2016Creep deformation and rupture behaviour of thermal aged P92 steel have been investigated over a stress range of 110–130 MPa at 923 K. Laves phase was observed in the thermal aged steel. Laves phase predominantly coarsens towards the intra-lath region assisted by substructure within the lath region.

Analysis of the Creep Behavior of P92 Steel Welded Joint
Journal of Materials Engineering and Performance, 2011Different regions of heat-affected zone (HAZ) were simulated by heat treatment to investigate the mechanisms of the Type IV fracture of P92 (9Cr-2W) steel weldments. Creep deformation of simulated HAZ specimens with uniform microstructures was investigated and compared with those of the base metal (BM) and the weld metal (WM) specimens.

Unified description of tensile work hardening behaviour of P92 steel
Materials Science and Engineering: A, 2016Abstract Tensile work hardening behaviour of P92 steel has been examined over wide range of temperatures (300–923 K) and strain rates (3.16×10 −5 –1.26×10 −3 s −1 ) in terms of the variations of instantaneous work hardening rate ( θ ) with true stress ( σ ) and true plastic strain rate ( e p ). At all the temperatures and applied strain

Microstructural characterization of oxide scales formed on steels P91 and P92
Materials at High Temperatures, 2011AbstractIn this paper, an in-depth study of steam oxidation of two 9Cr ferritic-martensitic steels (P91 and P92), for advanced power plant, has been carried out. The steels investigated were exposed to a 100% flowing steam environment at 650°C for 1,000 – 3,000 hours.

Creep Properties Assessment of P92 Steel by Small Punch Creep Tests
Transactions of the Indian Institute of Metals, 2015Small punch creep (SPC) tests have the potential as an alternative to conventional uniaxial creep tests when limited amount of material is available. This paper investigates the applicability of SPC to evaluate the creep deformation behavior of P92 steel.

Hot deformation behaviour and constitutive modelling of P92 heat resistant steel
Materials Science and Technology, 2011Hot compression tests are conducted in the present paper to investigate hot deformation behaviour of the newly developed heat resistant steel P92, which is used to fabricate main steam pipes for ultra supercritical power plants. Stress–strain curves at elevated temperatures and different strain rates are obtained.
