Improving tribological properties of P91 steels through carburizing process
Materials Today: Proceedings, 2020Abstract The wear conduct of P91 steel has been researched under a dry sliding contact at consistent load. It was discovered that Carburizing was successful in improving the wear conduct of P91 steel material. A low temperature carburizing was completed for three distinct examples at an hour, an hour and a half and 120 min.

Structural stability of dissimilar weld joints of steel P91
Science and Technology of Welding and Joining, 2001The present paper addresses the issue of carbon and nitrogen redistribution in weld joints between creep resistant chromium steels. The redistribution of carbon and nitrogen was measured using the wave dispersive X-ray method. The conditions of the long term diffusion annealing process were: temperature 575, 625, and 700°C; and time 10, 100, 1000, and

Microstructural changes in creep exposed P91 steel weld joint
Materials at High Temperatures, 2011AbstractCast plates made of 9Cr – 1MoV creep resistant steel were joined together using the GTAW and SMAW methods. Creep testing was carried out at a temperature range from 525°C to 625°C and a stress range from 50 to 240MPa. The microstructure of crept specimens was compared with weld joint at conditions after PWHT and the base material before welding.

Grain Refinement of P91 Steel Using Double Austenitization Treatment
Materials Performance and Characterization, 2018Abstract The effect of conventional normalizing and tempering (CNT) and double austenitization–based normalizing and tempering (DNT) heat treatments on the microstructure evolution and mechanical properties of creep strength–enhanced ferritic P91 steel were studied.

Modeling the Creep Damage of P91 Steel Using Peridynamics
Volume 9: Mechanics of Solids, Structures, and Fluids, 2019Abstract Creep is an important failure mechanism of metal components working at a high temperature. To ensure the structural integrity and safety of systems working at high temperature it is essential to predict failure due to creep. Classical continuum based damage models are used widely for modeling creep damage.

Cyclic softening of tempered ferritic-martensitic steel P91
2015For the ferritic-martensitic steel P91 cyclic softening has been identified as important factor in the assessments of creep-fatigue in nuclear components. Better understanding of the cyclic softening is needed as it is believed to be the main contributor for the complex material behavior encountered in creep-fatigue testing.
