20090263266 | L12 strengthened amorphous aluminum alloys - An improved amorphous aluminum alloy having high strength, ductility, corrosion resistance and fracture toughness is disclosed. The alloy has an amorphous phase and a coherent L1 | 10-22-2009 |
20100061876 | DYNAMIC DEHYDRIDING OF REFRACTORY METAL POWDERS - Refractory metal powders are dehydrided in a device which includes a preheat chamber for retaining the metal powder fully heated in a hot zone to allow diffusion of hydrogen out of the powder. The powder is cooled in a cooling chamber for a residence time sufficiently short to prevent re-absorbtion of the hydrogen by the powder. The powder is consolidated by impact on a substrate at the exit of the cooling chamber to build a deposit in solid dense form on the substrate. | 03-11-2010 |
