Description
  • Creep behavior and degradation of creep properties of advanced 9-12%Cr ferritic steels are phenomena of major practical relevance, often limiting the lives of power plant components and structures designed to operate for long periods under stress at elevated temperatures. Because life expectancy is, in reality, based on the ability of the material to retain its high- temperature creep strength for period of the least twice the projected design life, methods of creep property assessment based on physical changes in the material that are likely to occur during service exposure rather than simple parametric extrapolation of the short-term data are necessary. This work attempts to highlight the problem areas just in this respect. The proposed approaches are illustrated by recent experimental results on advanced high creep strength 9-12%Cr ferritic-martensitic steels (P91 and P92).

  • Creepové chování a degradace creepových vlastností pokročilých 9-12%Cr feritických ocelí jsou hlavní pojmy důležité v praxi, které často ovlivňují životnost komponent a zařízení určených k dlouhodobé exploataci pod napětím při zvýšených teplotách. Jelikož pravděpodobná životnost je ve skutečnosti založena na schopnosti materiálu podržet vysokoteplotní pevnost po dobu nejméně dvojnásobné projektované životnosti, metody odhadu creepových vlastností založené na fyzikálních změnách materiálu při dlouhodobé expozici jsou věrohodnější než jednoduchá parametrická extrapolace krátkodobých creepových dat. Tato práce se pokouší tento problém objasnit právě v tomto ohledu. Navrhované přístupy jsou ilustrovány nedávnými experimentálními výsledky získanými na pokročilých vysoce creepově odolných 9-12%Cr feriticko-martenzitických ocelích (P91 a P92). (cs)
