Claims20
A titanium alloy consisting essentially of titanium and carbon,
- wherein said carbon comprises 0.2 to 4 weight percent of said titanium alloy, and
- wherein a microstructure of said titanium alloy comprises islands of carbon or intermetallic carbon compounds having a cross-sectional diameter of at least 3 micrometers.
A titanium alloy consisting essentially of titanium, carbon, and oxygen,
- wherein said carbon comprises 0.2 to less than 0.5 weight percent of said titanium alloy, and said oxygen comprises up to 0.12 wt. % of said titanium alloy.
A titanium alloy consisting essentially of titanium, carbon, and oxygen,
- wherein said carbon comprises greater than 1.5 to 4 weight percent of said titanium alloy, and said oxygen comprises up to 0.12 wt. % of said titanium alloy.
A titanium alloy consisting essentially of titanium, carbon, and silicon,
- wherein said carbon comprises 0.2 to 4 weight percent of said titanium alloy, and said silicon comprises 0.1 to 0.5 weight percent of said titanium alloy, and
- wherein a microstructure of said titanium alloy comprises islands of carbon or intermetallic carbon compounds having a cross-sectional diameter of at least 3 micrometers.
A titanium alloy consisting essentially of titanium, carbon, silicon, and oxygen,
- wherein said carbon comprises 0.2 to 4 weight percent of said titanium alloy, said silicon comprises 0.1 to 0.5 weight percent of said titanium alloy, and said oxygen comprises up to 0.2 wt. % of said titanium alloy, and
- wherein a microstructure of said titanium alloy comprises islands of carbon or intermetallic carbon compounds having a cross-sectional diameter of at least 3 micrometers.
