1. 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 1850° C.; and forging the congruently melting alloy into a flexure having a circular body and a plurality of attachment arms arranged on the circular body to couple the flexure to an optical element.
