Abstract
The combined effects of cerium and boron additions on the room-temperature tensile properties and high-temperature oxidation behaviour of Ni3Al alloys: alloy 1 doped with cerium, alloy 2 doped with boron, and alloy 3 doped with both cerium and boron. The strength, ductility and oxidation behaviour of the alloy are more effectively improved by combined cerium and boron additions than by cerium or by boron addition alone. Of the three alloys, alloy 3 exhibits comprehensively the best mechanical properties and oxidation resistance. Alloy 2 presents the better mechanical properties than alloy 1; nevertheless, alloy 1 has the better oxidation resistance than alloy 2.
