The high resistance of iron aluminides to sulfidizing and oxidizing environments at high temperatures offers potential for structural application as lower cost alternatives to 300 and 400 series stainless steels and some nickel-base alloys. They are, however, subject to ductility limitations at room temperature which compel careful processing in order to achieve optimum properties in the final product. The standard melt-processing route of casting to ingot followed by hot and warm working to bar, plate or sheet is critically dependent on, for example, control of grain size in the initial cast structure, and the low ductility of the ingot structure at room temperature rules out cold working as a possibility at that stage. The purpose of this contribution is to report results of initial trials involving strip casting from the melt followed directly by cold-rolling and heat treatment. A previous communication reported results of an alternative novel route, that of co-rolling of elemental foils followed by heat treatment.
