In the context of Fe-15Mn-9Al-5Ni-0.8C (wt.%) steel after solution treatment at 1250 ᵒ C for 35 mins followed by subsequent annealing at 1050 ᵒ C for 5 mins, heating rate has been reported to influence the morphology and distribution of B2 precipitates in FCC matrix . It was shown that a low heating rate (~2.5 °C/s) leads to (i) an increase in the volume fraction, and (ii) a uniform distribution of B2 precipitates in FCC matrix and GBs (in Fe-15Mn-9Al-5Ni-0.8C (wt.%) steel) (Fig. )) ). On the contrary, high heating rate (~ 7.5 °C/s) was reported to reduce the volume fraction of B2 precipitates in FCC matrix and GBs (as shown in Fig. )). Fig.
