ALLOY RESISTANT TO OXIDATION AND CORROSION FOR CONSTRUCTIVE PARTS WORKING IN MEDIUM TEMPERATURE RANGE BASED ON {FEI3AL}

摘要

Oxidation- and corrosion-resistant alloy for components for a medium temperature range based on doped iron aluminide Fe3Al having the following composition: Al=24-28 at.-% Nb=0.1-2 at.-% Cr=0.1-10 at.-% B=0.1-1 at.-% Si=0.1-2 at.-% Fe=remainder. At 550 DEG C. high temperature yield points of 500 to more than 650 MPa are obtained.
