This paper reviews the laws in microstructure transformation and the mechanical properties changing for T/P92 steel during the aging and creep exposure process at high temperature.The precipitation sequences of various carbides and their variations in size and morphology are discussed in detail
as well as the inner link between the microstructure and the mechanical properties.Besides
the reasons for decline in creep strength and premature failure for T/P92 are discussed in terms of precipitations evolution
lath martensite degradation
alloying elements diffusion and so on.Finally
the methods for creep life prediction are reviewd and forecast.
