Abstract
Methods for producing forged products and other worked products are disclosed. In one embodiment, a method comprises using additive manufacturing to produce a metal shaped-preform and, after the using step, forging the metal shaped-preform into a final forged product. The final forged product may optionally be annealed.
Claims20
A method comprising:
- (a) using additive manufacturing to produce a metal shaped-preform, wherein the metal shaped-preform comprises a nickel alloy, wherein the additive manufacturing comprises:
- depositing layers of a first material on an upper side of a building substrate;
- and
- depositing layers of a second material on an opposing lower side of the building substrate;
- wherein at least one of the first material, the second material and the building substrate comprises the nickel alloy;
- (b) after the using step (a), forging the metal shaped-preform, with the building substrate therein, into a final forged product having the building substrate therein;
- wherein the forging step (b) comprises non-uniformly applying strain to the metal shaped-preform via an impression die.

A method comprising:
- (a) using additive manufacturing to produce a metal shaped-preform, wherein the metal shaped-preform comprises an aluminum alloy, wherein the additive manufacturing comprises:
- depositing layers of a first material on an upper side of a building substrate;
- and
- depositing layers of a second material on an opposing lower side of the building substrate;
- wherein at least one of the first material, the second material and the building substrate comprises the aluminum alloy;
- (b) after the using step (a), forging the metal shaped-preform, with the building substrate therein, into a final forged product having the building substrate therein;
- wherein the forging step (b) comprises non-uniformly applying strain to the metal shaped-preform via an impression die.

A method comprising:
- (a) using additive manufacturing to produce a metal shaped-preform, wherein the metal shaped-preform comprises a titanium alloy, wherein the additive manufacturing comprises:
- depositing layers of a first material on an upper side of a building substrate;
- wherein at least one of the first material and the building substrate comprises the titanium alloy;
- wherein the building substrate is a pre-wrought base plate;
- and
- (b) after the using step (a), forging the metal shaped-preform, with the building substrate therein, into a final forged product having the building substrate therein;
- wherein the forging step (b) comprises non-uniformly applying strain to the metal shaped-preform via an impression die.
