Creators
Description
This patent describes a niobium-based superalloy composition. It comprises 0 to 1 percent of a corrosion inhibitor-mechanical strengthener selected from the group consisting of an element from the lanthanide and actinide series of the periodic table, scandium, yttrium, lanthanum, and mixtures thereof; 0.001 to 10 percent of an additive element selected from the group consisting of rhenium, technetium, and mixtures thereof; and the balance of the superalloy composition being essentially niobium, the superalloy composition having improved resistance to high temperature oxidation of its niobium content
