ABSTRACT:
A substantial gain in the properties of conventional FeCrAlY is achieved by adding RuAl to a melt of the conventional material. The resultant composition has a use temperature above the melting point of nickel base superalloys and has good strength and ductility properties to permit its use as a high temperature structural material.
