Articles, including such gas turbine engine hardware as airfoils and discs, are formed by forging alloys in a temporary condition of low strength and high ductility around suitable supporting materials or shapes, and forming a composite by diffusion bonding. The supporting materials may be retained within the finished article to provide, for example, a filament strengthened composite or may subsequently be leached therefrom to form hollow hardware. |
