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.).
Claims7
A method of making a composite part, the method comprising:
- depositing a blend of a first alloy powder and a second metallic alloy powder onto a surface,
- the first alloy powder including, about 13.5 to about 14.5 wt. % zirconium, about 18 to about 19 wt. % niobium, and a congruently melting alloy of titanium, wherein titanium makes up a majority of the first alloy powder when melted forming a 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;
- wherein blend is deposited at each repetition such that the composite part includes a gradient of the first alloy and the second metallic alloy along the composite part by adjusting a feed rate of at least one of the first alloy powder or the second metallic alloy powder.
