Abstract:

Five different amorphous alloys have been prepared at Battelle for the purpose of studying localized corrosion. The compositions of these alloys are shown in Table 1. The alloys were prepared by first vacuum melting proper quantities of appropriate high purity components and casting into conventional ingots. Several other alloys are included in the study for various reasons. These alloys and their compositions are shown in Table 2. The Metglas compositions were chosen to incorporate amorphous compositions prepared by a source other than Battelle. T304 stainless steel is being used because it exhibits classical pitting and crevice corrosion in halide-containing electrolytes. Incoloy 800 was selected because it represents a conventional crystalline alloy of similar Fe, Ni, and Cr content as Alloy 5, and thereby furnishes an indication of the corrosion behavior provided by these elements in the crystalline rather than amorphous state.
