Title: Oxidation-sulfidation behavior of Fe-Cr-Ni-Zr alloys in mixed-gas environments

Austenitic Fe-Cr-Ni alloys can undergo either oxidation or sulfidation upon exposure to oxygen-sulfur mixed-gas environments at elevated temperatures. A threshold oxygen partial pressure of three to five orders of magnitude in excess of the value for Cr oxide/Cr sulfide equilibrium is required for development of a continuous protective oxide scale. The present work involves thermogravimetric studies on several Fe-Cr-Ni alloys with additions of 1 to 6 wt % zirconium. Experimental results are presented on the oxidation-sulfidation behavior of these alloys in air, low-oxygen, and oxygen-sulfur environments.
