abstract = {A series of G-phase strengthened ferritic stainless steels
Fe-20Cr-3Ni-3Si-X (X = 2Mn, 1Mn-2Ti, 1Mn-2Nb and 1Mn-2Ta)
are characterized after aging using experimental
(microhardness, TEM and APT) and theoretical (DFT)
techniques. The results indicate that the Ni16Mn6Si7 G-phase
shows sluggish precipitation during aging treatment. This
was attributed to the small difference in the enthalpy of
formation between the Ni16Mn6Si7 G- and BCC phase and the
requirement of high Ni:Fe ratio. A superfine Ni16Ti6Si7
G-phase was found to precipitate as a core accompanied with
an “envelope” of Fe2TiSi-L21 Heusler phase during early
aging (≤24 h) in the Ti containing alloy. This morphology
is predicted to occur due to early Ni clustering in ferrite
and a negative Ni concentration gradient away from the
cluster that favors Fe2TiSi formation. The G-phases show
only particle coarsening without obvious chemical
composition evolution for further aging up to 96 h. A
prominent hardness increase of 100-275 HV was also observed
during aging. These findings provide valuable insight into
methods for precipitating low lattice mismatch silicide
phases for the development of future high strength steels.},
