Abstract

A highly corrosion-resistant amorphous alloy containing 10 to 40 atom % of Ta and also Mo, Cr, W, P, B, Si, etc. is disclosed. This alloy can be produced by super-quenching and solidifying molten metal, and shows a good corrosion resistance in a high-temperature, conc. phosphoric acid, thus being suited to be used as the structural material of a plant where phosphoric acid is used and as the separator for fuel cells.
