SRO was suggested in Alloy 690 with 9.18 wt% Fe after thermal ageing at 350, 420 and 475 °C. Prior thermal treatment promoted SRO before ageing. Cold work led to recrystallization and precipitation of α-Cr upon ageing at 550 °C. Thermal ageing promoted IG precipitation of Cr-rich M23C6 carbides and DIGM.
