Recrystallisation Temperatures in Mechanically Alloyed Oxide-Dispersion-Strengthened MA956 and MA957 Steels

T. S. Chou and H. K. D. H. Bhadeshia


Previous work has demonstrated that the mechanically alloyed oxide-dispersion-strengthened steels MA956 and MA957 have significantly different crystallographic textures prior to recrystallization and that their subsequent recrystallization behaviours are also not similar. New experiments confirm that the differences in recrystallization behaviour can indeed be attributed to their initial difference in crystallographic texture. The crystallographic texture of MA957 prior to recrystallization has been manipulated so as to make it similar to that of MA956, and the two alloys have been demonstrated to behave similarly during subsequent recrystallization heat treatments.
