Elastoplastic Fracture Analysis of the P91 Steel Welded Joint under Repair Welding Thermal Shock Based on XFEM

Metals, 2020
P91 steel is a typical steel used in the manufacture of boilers in ultra-supercritical power plants and heat exchangers in nuclear power plants. For the long-term serviced P91 steel pressurized structures, the main failure mode is the welded joint ...

Boro-aluminising of P91 steel by pack cementation for protection against steam oxidation [PDF]

, 2011
High performance alloys are often the materials used for various components exposed to high temperature environments. In many cases, protective coatings are applied in these alloys, providing higher corrosion and oxidation resistance, compared to the ...

Examining Stress Relaxation in a Dissimilar Metal Weld Subjected to Postweld Heat Treatment [PDF]

, 2018
Dissimilar metal welds are often required in nuclear power plants to join components made from austenitic steels to those from ferritic steels, particularly in fast breeder reactor plants, in order to join the intermediate heat exchanger to the steam ...

Recommendation for the negligible creep domain for P91 [PDF]

, 2016
The report is a recommendation on the methodology for determining the negligible creep (NEC) domain for P91 steel. The objective to define the actual TNEC curve for P91 was fully reached and time safety factors involved in the recommended curve was ...

Creep-fatigue crack growth behaviour of P91 steels

Procedia Structural Integrity, 2016
AbstractThe importance of predicting failure due to combined creep-fatigue crack growth in high temperature power-plant components has become of great importance importance due to the need for plant to ‘load follow’ in response to fluctuations in demands and the availability of renewables.

The influence of coupling effect between stress and high temperature on the degradation of microstructure and hardness in P91 steel

Materials & Design
Interrupted aging and creep tests were performed in the condition of 650 °C/70 MPa for P91 steel. The mechanisms of hardness and microstructure evolution during aging and creep were studied through hardness test, SEM/EBSD and TEM/EDS.
