Abstract
Systems and methods for enhancing the cold-formability of Ti 6-2-4-2 sheet material are described herein. Embodiments of these methods comprise cold-forming a predetermined, pretreated Ti 6-2-4-2 alloy into a cold-formed shape; subjecting the cold-formed shape to a post-forming annealing cycle comprising: heating the cold-formed shape to about 1450±25 ° F.; holding the cold-formed shape at about 1450±25° F. for about 15±2 minutes; and cooling the cold-formed shape to room temperature. Embodiments of these methods further comprise subjecting the predetermined Ti 6-2-4-2 alloy to a pre-forming annealing cycle comprising: heating the predetermined alloy to a pre-forming annealing temperature of about 1550-1750° F.; holding the predetermined alloy at the pre-forming annealing temperature for about 30 minutes; and cooling the predetermined alloy to room temperature. These methods allow components comprising 90° bend angles, having a bend factor as low as about 6.2 T, to be achieved.
