A titanium article having improved corrosion resistance resulting from a direct or indirect attachment of a platinum group metal or alloy thereof or incorporation of this metal or alloy thereof into a minor surface portion of the article.

Fabricated titanium article having improved corrosion resistance

A titanium article having improved corrosion resistance resulting from an appliqu&eacute; of a platinum group metal or alloy thereof attached to a minor surface portion of the article.

Titanium article having improved corrosion resistance

An alpha-beta titanium-base alloy having a good combination of strength and ductility with a relatively low cost composition. The composition, in percent by weight, is 5.5 to 6.5 aluminum, 1.5 to 2.2 iron, 0.07 to 0.13 silicon and balance titanium. The alloy may have oxygen restricted in an amount up to 0.25%. The alloy may be hot-worked solely at a temperature above the beta transus temperature of the alloy to result in low-cost processing with improved product yields. The hot-working may include forging, which may be conducted at a temperature of 25.degree. to 450.degree. F. above the beta transus temperature of the alloy. The hot-working may also include hot-rolling, which also may be conducted at a temperature of 25.degree. to 450.degree. F. above the beta transus temperature of the alloy.

Alpha-beta titanium-base alloy and method for processing thereof

An alpha-beta titanium-base alloy, and fastener made therefrom. The alloy has a combination of an ultimate tensile strength of at least 220 ksi with a minimum elongation of 7% in the solution-treated and aged condition. The alloy has a total beta stabilizer content of 15 to 20%, a total alpha stabilizer content of 1.5 to 3.5% and balance titanium. The alloy may have an aluminum equivalence of at least 3.0%, preferably 4.0%. The alloy may have an aluminum content of at least 1.5%. The beta stabilizer element may be at least one vanadium, molybdenum or iron and the alpha stabilizer element may be one or more of aluminum, oxygen, carbon and nitrogen.
