Abstract:
The method of the present invention improves the density, strength and bonding of coatings which have previously been applied to substrates by prior art methods such as chemical deposition, electrochemical processed, thermal deposition, and mechanical coating. The method of the present invention subjects the coated substrate to a thermal mechanical process in the form of a compressive stress which is applied to the coating at a temperature greater than about 0.5 T.sub.i and less than T.sub.i where T.sub.i is the incipient melting temperature. The compressive stress is preferably applied through a pressure transfer medium and should be greater in magnitude than about 30 ksi. The dwell time under maximum compressive stress can be from about 0.1 second to about 10 seconds depending on the temperature of the coating, the substrate and the magnitude of the compressive stress.
Abstract:
The present invention relates to a method of manufacturing widgets from components and/or particulate; and to a can for containing such components and/or particulate during the consolidation into widgets. The method of the present invention can be used to form widgets from metals, ceramics, plastics, polymers, and/or combinations thereof. The materials used to form the widgets can be in the form of particulate, pellets, shard, and/or ribbon. The method of the present invention can also be used to join widgets and/or to heal ingot cracks.
Abstract:
The present invention is for an improved aluminum alloy powder for making consolidated products with an improved combination of strength and ductility. The alloy is cast as ribbon or flake which subsequently pulverized.
Abstract:
Techniques for backup and restore of optimized data streams are described. A chunk store includes each optimized data stream as a plurality of chunks including at least one data chunk and corresponding optimized stream metadata. The chunk store includes data chunks in a deduplicated manner. Optimized data streams stored in the chunk store are identified for backup. At least a portion of the chunk store is stored in backup storage according to an optimized backup technique, an un-optimized backup technique, an item level backup technique, or a data chunk identifier backup technique. Optimized data streams stored in the backup storage may be restored. A file reconstructor includes a callback module that generates calls to a restore application to request optimized stream metadata and any referenced data chunks from the backup storage. The file reconstructor reconstructs the data streams from the referenced data chunks.
Abstract:
The present invention is for a device for rapidly solidifying a material and a method of using the same. The device provides for containing a molten pool of material in a solid skull with the same composition as the molten material. The skull is preferably held in a cavity of an inductor which is heated by an induction coil. Means are provided to maintain a small temperature gradient in the skull so as to minimize segregation which can lead to compositional fluctuations. It is preferred that the minimum temperature in the skull is between about 0.7 and 0.95Tm, where Tm is the melting or solidus temperature of the material.Feed means provide material to the molten pool causing it to spill over onto a moving chill surface. Preferably the chill surface is cooled by a molten stream of liquid gas.

Abstract:
A method for recovering a usable alloy consisting of 2.5 - 3.5% aluminum, 1.7 - 2.50% tin and balance titanium from titanium scrap is disclosed. The method comprises cleaning the scrap, charging the cleaned scrap into an electron beam furnace and refining the charge under a hard vacuum so as to attain a predetermined composition.
