Abstract
To improve the oxidation resistance of a remelted zone in Al2O3-forming austenitic stainless steels, effects of annealing temperature on microstructural evolution and Al2O3 formation in remelted zone of Fe–25Ni–10Cr–5Al–1Nb–Y steel (wt%) were investigated. The results showed that a continuous Al2O3 film could not form in the remelted zone before annealing. After annealing at 1,100, 1,150 and 1,180 °C, a continuous Al2O3 film formed. The existence of a second phase containing Al is the key for the formation of a continuous Al2O3 film. The thickness of Al2O3 film increased with the rise in Al content in the second phase.
