Abstract
The present invention relates to methods of multi-axis forging to refine a grain size of a workpiece comprising a titanium alloy selected from Ti-6A1-25n-4Zr-6Mo alloy (UNS R56260), Ti-4AI-2.5V alloy (UNS R54250 / ATI 425 / Grade 38), Ti-6AI-7Nb alloy (UNS R56700), and Ti-6AI-6V-2Sn alloy (UNS R56620), the method comprises beta annealing the workpiece; cooling the beta annealed workpiece to a temperature below a beta transus temperature of the titanium alloy; and multi-axis forging the workpiece as recited herein, and repeating at least one of the press forgings until a total true strain of at least 1.0 up to less than 3.5 is achieved in the workpiece. The invention aims to provide a process for producing titanium alloys having coarse, fine, very fine, or ultrafine grain microstructure that does not require multiple reheats, accommodates higher strain rates, reduces the time necessary for processing, and/or eliminates the need for custom forging equipment.
