Abstract: The alloy is based on doped iron aluminide Fe3Al. It contains the following alloy constituents, in atomic per cent: 24 - 28 of aluminium 0.1 - 2 of niobium, tantalum and/or tungsten 0.1 - 10 of chromium 0.1 - 2 of silicon 0.1 - 5 of boron 0.01 - 2 of titanium the remainder being iron. The alloy is distinguished, even at temperatures above 700@C, by a high oxidation resistance and corrosion resistance and is preferentially used in components which are exposed to oxidising and corroding effects at high temperatures and low mechanical stress.
