Abstract
A method for accelerating the creep age forming of a metallic component is provided. The method includes the steps of applying static loading and ultrasound vibrations to the local regions on a metallic component during the creep age forming process. The transmission of ultrasound in the component enhances the mobility of dislocations and atoms and thus accelerates the creep deformation in the component.
Claims3
A method for accelerating creep age forming process for making a final component having curved geometry from a flat sheet metal, the method comprising the steps of:
- preparing at least one elongated sonotrode, the sonotrode comprising a first end and a second end, the first end connected to an ultrasound system and the second end comprising a tip;
- providing a least one former having a curved surface;
- preparing a loading device to each sonotrode;
- placing the flat sheet metal on said at least one former;
- placing each sonotrode to each location where accelerated creep deformation is required, with the sonotrode at one side and the former at the opposite side of the flat sheet metal at that location;
- brining the flat sheet metal to predetermined temperatures;
- and
- applying loading to cause creep deformation in the component and applying ultrasonic vibrations through the sonotrode to the flat sheet metal at predetermined rates and times to accelerate local creep deformation until the flat sheet metal reaches its desired profile.
