Abstract
An optical mount part having a body that includes a composite of a titanium-zirconium-niobium alloy. The titanium-niobium-zirconium alloy includes titanium, about 13.5 to about 14.5 wt. % zirconium, and about 18 to about 19 weight % (wt. %) niobium. The titanium-niobium-zirconium alloy has a congruent melting temperature of about 1750 to about 1800° Celsius (° C.).
Claims20
An optical mount part comprising:
- a body including a composite of a titanium-zirconium-niobium alloy comprising titanium, about 13.5 to about 14.5 wt. % zirconium, and about 18 to about 19 weight % (wt. %) niobium, the titanium-zirconium-niobium alloy having a congruent melting temperature of about 1750 to about 1800° Celsius (° C.).
A powder mixture comprising:
- a composite blend of a titanium-zirconium-niobium alloy particles including titanium, about 13.5 to about 14.5 wt. % zirconium, and about 18 to about 19 weight % (wt. %) niobium, the titanium-zirconium-niobium alloy having a congruent melting temperature of about 1750 to about 1800° C.
A method of making a composite part, the method comprising:
- depositing a blend of a first alloy powder and a second powder onto a surface, the first alloy powder including a congruently melting alloy of titanium, about 13.5 to about 14.5 wt. % zirconium, and about 18 to about 19 wt. % niobium, the congruently melting alloy having a congruently melting temperature of about 1750 to about 1800° C.;
- melting the blend to form a first layer including a composite;
- and
- repeating the depositing and the melting to form a plurality of successive layers to build up the composite part.
