Low-cycle fatigue life of steel P92 under gradual loading
IOP Conference Series: Materials Science and Engineering, 2012 The aim of the study was to determine low-cycle fatigue life characteristics of P92 steel used in the power unit components that work under the highest effort. Steel service life was determined in the tests for total fixed strain Δet ranges from 0.6 to 1.2 % and with application of two-stage sequence loading.

Characterization of viscoplasticity behaviour of P91 and P92 power plant steels [PDF]
International Journal of Pressure Vessels and Piping, 2013 This paper deals with the determination of material constitutive model for P91 and P92 steels at high temperatures. An isothermal, strain-controlled test programme was conducted for both steels for a temperature range between 400 and 675 °C. The experimental data from these tests were used to obtain the material constants in a viscoplasticity model ...
