Fig.5. Low (a~c) and high (d~f) magnified SEM morphologies of the interdendritic β phase in alloy subjected to 1200?℃, 10?h solution treatment and cooled at water cooling (138?℃/s) (a, d), air cooling (72?℃/s) (b, e) and furnace cooling (0.05?℃/s) (c, f), revealing the effects of cooling rate on the evolution of the interdendritic β-matrix and interior precipitates (SFs—stacking faults) [73]
