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.

High temperature fatigue and cyclic creep of P91 steel
2002Abstract Cyclic plastic response of martensite ferritic 9%Cr steel was investigated at 600°C under symmetrical and asymmetrical loading. Cyclic softening was found to be the main characteristic cyclic deformation feature. The tensile mean stress promotes the cyclic plasticity and results in cyclic creep. Fatigue loading with 2Hz frequency reduces the

Behaviour of P91 Steel Simulated Haz at 600°C
2011An investigation has been carried out into the behaviour of type IV cracks region in heat affected zone (HAZ) of P91 steel at 600°C. Microstructure zones where type IV failures may occur have been studied in details. Results are reported on the simulated specimens 11x11x70 mm tested at operating temperature.
