Abstract
Oxidation- and corrosion-resistant alloy for components for a medium temperature range based on doped iron aluminide Fe.sub.3 Al having the following composition: PA1 Al=24-28 at.-% PA1 Nb=0.1-2 at.-% PA1 Cr=0.1-10 at.-% PA1 B=0.1-1 at.-% PA1 Si=0.1-2 at.-% PA1 Fe=remainder. At 550.degree. C. high temperature yield points of 500 to more than 650 MPa are obtained.
