Abstract
An oxidation- and corrosion-resistant high-temperature alloy of high toughness at room temperature for directional solidification, based on an intermetallic compound of the nickel aluminide type and having the following composition: PA1 Al=10-20 atom % PA1 Si=0.5-8 atom % PA1 Nb=2-10 atom % PA1 B=0.1-2 atom % PA1 Ni=remainder, the total of Al, Si, Nb and B amounting at most to a value of 25 atom %. The alloy contains at least 90% by volume of the intermetallic phases Ni.sub.3 Al, Ni.sub.3 Si and Ni.sub.3 Nb.
