Abstract
Substantially defect-free titanium aluminide components and methods are provided for manufacturing the same from articles formed by consolidation processes. The method includes providing an intermediate article comprised of a titanium aluminide alloy and formed by a consolidation process. The intermediate article is encapsulated with an aluminum-containing encapsulation layer. The intermediate article is compacted after the encapsulation step. A substantially defect-free titanium aluminide component comprises a compacted three-dimensional article comprised of titanium aluminide and formed by a consolidation process and an aluminum-containing encapsulation layer on at least one surface of the compacted three-dimensional article. The aluminum-containing encapsulation layer comprises an aluminide material, MCrAlY wherein M is cobalt, nickel, or a combination of cobalt and nickel, or TiAlCr.
