Fig.6. Inverse pole figure (IPF) of the two phase microstructure that deformed at 550℃ is presented in (a), and the electronic polished surface is showed in (b). After tension at 550℃ and 650℃, precipitation statuses of the ferritic grains in the two phase microstructure are presented in (c) and (d), respectively. EDS results of the typical precipitates are listed in (e)
