Abstract: In ODS nickel-base alloys with high r'-content (e.g. MA760) the rate of heating to the recrystallization temperature plays an important role for the success of the recrystallization treatment. Previous results (Jongenburger et al., 1990) revealed the existence of a heating rate window for secondary recrystallization. While the lower limit of this window (Tmin) is well understood, an attempt is made in this paper to explain the upper limit (Tmax) by the influence of carbide phases. Furthermore it is shown that carbide phases may also influence the incipient melting temperature and consequently the width of the temperature window for successful secondary recrystallization.
