The cyclic-oxidation behavior of a "low-nickel austenitic stainless steel"
(LNiSS) at 873 and 973 K has been investigated up to 500 cycles. A wide ran
ge of experimental techniques, including SEM, EDS, and XRD have been applie
d to examine the oxide scales. After cyclic oxidation at 873 and 973 K, the
new LNiSS alloy showed good oxidation resistance. XRD and EDS analysis sho
w that composition of oxide scales developed during cyclic oxidation at 873
and 973 K are the same. The oxide scales formed a cubic oxide-type M2O3 an
d a cubic spinel-type M3O4 adhered well to the substrate.
