英文摘要
Long-term creep life is estimated by time-temperature-parameter (TTP) methods. Such TTP methods overestimate creep life of creep strength enhanced ferritic (CSEF) steels. Decrease in activation energy Q for creep life in long-term creep of the steel is shown to be the cause of the overestimation. Creep life data of CSEF steel are divided into several data sets so that Q is unique in each divided data set, and then analyzed by a TTP method for creep life estimation. It has been proved that this multi-region analysis can properly estimate long-term creep lives. In creep of CSEF steels, recovery process of dislocation substructure is different between short-term and lon-term creep. This change in damage processes is the major cause of the decrease in Q value in long term-creep.
