FORECASTING THE PARTICLE DIAMETER SIZE DISTRIBUTION IN P92 (X10CrWMoVNb9-2) STEEL AFTER LONG-TERM AGEING AT 600 AND 650 °CThe investigations on microstructure of P92 steel in the as-received condition and after 10 5 h ageing at 600 and 650 °C were carried out. For the recorded images of microstructure, the quantitative analysis of precipitates was performed.On that basis, a statistical analysis of collected data was made with the aim of estimating parameters of selected theoretical statistical distribution. Then, the forecast for average precipitate diameter and standard deviation of such a distribution for the time of 1,5*10 5 h at 600 and 650 °C was calculated. The obtained results of investigations confirm the possibility of using, in evaluation of degradation degree for materials in use, the forecasting methods derived from mathematical statistics, in particular the theory of stochastic processes and methods of forecasting by analogy.

“…They are also under active consideration as candidate materials for high temperature structural components of Generation IV nuclear power plants. [1,2] New ferritic P92 steel, also known as NF616 in Japan, is the most suitable material used for pipelines that serviced in ultra-supercritical (USC) plant. P92 steel has been developed by the addition of tungsten with molybdenum and other alloying elements, which have led to about 30% increase in creep rupture strength at 600 8C, compared with P91 steel.…”

“…[11][12][13][14][15] An et al [16] analyzed the creep behavior of different regions in P92 steel welded joint, results showed that fine-grained heat-affected zone had the highest creep strain rate. In [ addition, the influence of temperature and strain rate on tensile deformation and fracture of P92 steel were investigated by Choudhary et al [17] In order to better understand the mechanical and microstructural stability of P92 steel under uniaxial tension, Giroux et al [1] studied the phenomena of necking, damage, and grain size evolution. However, few studies are related to the LCF behavior of new ferritic P92 steel.…”

Low cycle fatigue (LCF) tests were performed at various strain amplitudes ranging from 0.2 to 0.8% to investigate the effects of strain amplitude on cyclic softening behavior and LCF lifetime of new ferrtic P92 steel. LCF tests were conducted under strain controlled in fully reversed manner with strain rate of 1.0 Â 10 À3 s À1 at high temperature of 650 8C. A novel fatigue life end criterion was adopted in this analysis. The effects of strain amplitude on the cyclic softening behavior, the evolution of plastic strain amplitude, hysteresis loop area and the fatigue life were discussed. Similar softening curves were achieved except for the strain amplitude of 0.2%. The evolution of hysteresis loop areas at the smaller strain range amplitude (less than 0.4%) is contrary to the larger ones. A modified life prediction model was proposed based on Coffin-Manson model and energy-based model, comparison of predicted lifetime and experimental data shows that the model gives a good estimation. In order to better understand the basic stress-strain behavior, time-independent cyclic plasticity model was used to represent the cyclic mechanical behavior of this steel. Comparison of the simulated and experimental results shows that the proposed model can give a reasonable prediction of stress-strain hysteresis loop for P92 steel at high temperature.
