| 20080308197 | Secondary processing of structures derived from AL-RE-TM alloys - A method for processing a metal part includes extruding an Al-RE-TM alloy to form an extruded part, heating the extruded part, and applying a compressive strain greater than about 50% on the heated part. | 12-18-2008 |
| 20080308610 | Hollow structures formed with friction stir welding - A hollow structure, and a method of forming the hollow structure, where the hollow structure includes first and second metal parts, the second metal part having an interior surface and a tapered support member extending from the interior surface. The hollow structure also includes a friction stir welded joint that extends through the first metal part and into the tapered support member. | 12-18-2008 |
| 20080311421 | Friction stir welded structures derived from AL-RE-TM alloys - A welded structure that includes first and second metal parts derived from Al-RE-TM alloys, which are secured together at a welded joint by friction stir welding. | 12-18-2008 |
| 20100068550 | HOLLOW STRUCTURES FORMED WITH FRICTION STIR WELDING - A hollow structure, and a method of forming the hollow structure, where the hollow structure includes first and second metal parts, the second metal part having an interior surface and a tapered support member extending from the interior surface. The hollow structure also includes a friction stir welded joint that extends through the first metal part and into the tapered support member. | 03-18-2010 |
| 20100247322 | INTERNALLY SUPPORTED AIRFOIL AND METHOD FOR INTERNALLY SUPPORTING A HOLLOW AIRFOIL DURING MANUFACTURING - A hollow airfoil and a method for manufacturing a hollow airfoil is provided. The method includes the steps of: providing a first airfoil portion, which first portion has a wall with an interior surface and an exterior surface, and one or more ribs extending out from the interior surface; providing a second airfoil portion having a wall with an interior surface and an exterior surface; wherein the first airfoil portion and the second airfoil portion have mating geometries in which the one or more ribs extend between the interior surfaces of the walls of the first and second airfoil portion to form at least one internal cavity defined by the interior surface of the first portion wall, one or more of the ribs, and the interior surface of the second portion wall, and wherein the airfoil includes at least one exterior port disposed in one of the first airfoil portion or the second airfoil portion, or is formed between the first and second airfoil portions, which at least one exterior port is in fluid communication with the at least one cavity; disposing a support material within the at least one internal cavity allowing the support material to be in contact with the one or more ribs, which support material is operative to structurally support the one or more ribs; attaching the first and second airfoil portions together; and removing the support material from the at least one internal cavity through the at least one exterior port. | 09-30-2010 |
| 20110204122 | HOLLOW STRUCTURES FORMED WITH FRICTION STIR WELDING - A hollow structure, and a method of forming the hollow structure, where the hollow structure includes first and second metal parts, the second metal part having an interior surface and a tapered support member extending from the interior surface. The hollow structure also includes a friction stir welded joint that extends through the first metal part and into the tapered support member. | 08-25-2011 |
