  • METHOD OF FABRICATING A PART MADE OUT OF TA6ZR4DE TITANIUM ALLOY
    Publication number: 20140286783
    Abstract: A method of fabricating a part made out of TA6Zr4DE titanium alloy including forging a blank in the alpha/beta domain to form a preform, hot die-stamping the preform to form a rough part in the beta domain of the titanium alloy, and heat treatment. During the die-stamping, the rough part is subjected throughout to local deformation c greater than or equal to 1.2, the die-stamping being terminated by immediate cooling at an initial cooling rate faster than 85° C./min. The method can be utilized to make a rotary part of a turbomachine.
