Abstract
A high strength titanium alloy or titanium aluminide metal foil having improved strength and density is produced, preferably in coilable strip form, by plasma-depositing the selected titanium-based material on a receiving surface, separating the deposited material from the receiving surface to provide two metal foil preforms each having a relatively smooth side as cast against the receiving surface and a relatively rough, opposite side as deposited from the plasma, disposing the two metal preforms together with the relatively rough sides of the two metal preforms in facing engagement with each other, and squeezing the two preforms together between pressure bonding rolls to metallurgically bond the preforms to each other and to consolidate the materials of the preforms to form a fully dense metal foil.
