ALPHA STABILIZED BLACK TITANIUM ALLOYS

ALPHA STABILIZED BLACK TITANIUM ALLOYS

A titanium alloy having a Ti-Zr-X-Y formulation, wherein the X component is a Group V or Group VI metal and the Y component is an alpha stabilizer selected from aluminum, tin, silicon, oxygen, carbon, and nitrogen, where the titanium alloy is capable of being blackened in an air, oxygen, or oxygen c...

Zusammenfassung:A titanium alloy having a Ti-Zr-X-Y formulation, wherein the X component is a Group V or Group VI metal and the Y component is an alpha stabilizer selected from aluminum, tin, silicon, oxygen, carbon, and nitrogen, where the titanium alloy is capable of being blackened in an air, oxygen, or oxygen containing environment. The alloy may have a yield strength of at least 100 ksi. The Y component may be oxygen above 1300 ppm. The Zr content may be greater than 22 weight percent. The alloy may have a lightness index of 46 or less on the CIELAB scale.
