Abstract
A flexure including a bipod strut pair extending from a base and a titanium-zirconium-niobium alloy, which includes titanium, about 13.5 to about 14.5 wt. % zirconium, and about 18 to about 19 weight % (wt. %) niobium. The titanium-zirconium-niobium alloy has a congruent melting temperature of about 1750 to about 1800° Celsius (° C.).
Claims20
A flexure comprising:
- a bipod strut pair extending from a base;
- wherein the flexure includes 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 flexure comprising:
- a circular body;
- and
- a plurality of attachment arms arranged on the circular body to couple the flexure to an optical element;
- wherein the flexure includes 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° C.
1 more element
A method of making a compliant mount or mechanism structure, the method comprising:
- forming a congruently melting alloy of titanium, about 13.5 to about 14.5 wt. % zirconium, and about 18 to about 19 wt. % niobium, a congruently melting temperature of the congruently melting alloy being about 1750 to about 1800° C.;
- and
- forging the congruently melting alloy to a predetermined shape.
