%X Considering the effect of intergranular carbides density, a modifiedmodel has been proposed to try to suit any common case of the fraction of theintergranular carbides to the total grain boundary less than 1, on the basis of theprevious model for the grain boundary precipitation strengthening. This modifiedmodel may be available to predict the changes in creep rate and its stress and tem-perature dependence of alloys by intergranular carbides.
