  • COMPONENT HOLE TREATMENT PROCESS AND AEROSPACE COMPONENT WITH TREATED HOLES
    Publication number: 20130260168
    Abstract: A method of treating a hole in a metallic component includes the following steps in sequence: forming an hole having a first diameter in the component; expanding the hole to a second diameter using a cold expansion process, so as to induce residual compressive stresses in the material surrounding the hole; shot peening the hole; and final machining the hole to a finished diameter.

  • METHOD FOR PRODUCING A BETA-PROCESSED ALPHA-BETA TITANIUM-ALLOY ARTICLE
    Publication number: 20090032152
    Abstract: A titanium-alloy article is produced by providing a workpiece of an alpha-beta titanium alloy having a beta-transus temperature, and thereafter mechanically working the workpiece at a mechanical-working temperature above the beta-transus temperature. The mechanically worked workpiece is solution heat treated at a solution-heat-treatment temperature of from about 175° F. below the beta-transus temperature to about 25° F. below the beta-transus temperature, quenched, overage heat treated at an overage-heat-treatment temperature of from about 400° F. below the beta-transus temperature to about 275° F. below the beta-transus temperature, and cooled from the overage-heat-treatment temperature.
