摘要： Three dimensionally large metallic structures comprised of submicron grain sizes are produced by a process which includes directing a supersonic powder jet against a substrate such that the powder adheres to the substrate and to itself to form a dense cohesive deposit. The powder jet may be comprised of refractory metal powders. The powder may be deposited by a supersonic jet and may be extruded by Equi channel angular extrusion.

摘要： A process to chemically refine and consolidate tantalum, niobium and their alloys to a fabricated product of net shape or near-net shape with higher throughput, more consistency, and lower manufacturing costs compared to prior art routes or rejuvenate damaged and deteriorated refractory metal parts. Powder metal is loaded into hoppers to be fed into laser forming/melting equipment. A suitable substrate is loaded into a laser forming/melting chamber onto which the powder will be deposited and consolidated in a point-scan process. As the powder is fed onto successive points of the surface of the substrate in linear traces, the laser is used to heat and partially melt the substrate and completely melt the powder. A combined deposition and melt beam traces the substrate surface repeatedly over a selected area to build up a dense coating of controlled microstructure in multiple layers. A fully dense deposit is built up that becomes the desired shape.

摘要： Tantalum electrode material is produced which has extremely low tortuosity, exceptionally low ESL and ESR, potentially extended high frequency performance, very high volumetric efficiency, and reduced tantalum consumption per electrode. The electrode material is characterized by having a cross-section composed of plates of tantalum separated by spaced gaps resulting in a highly dense (volumetric efficiency) electrode. The plates are electrically interconnected which also adds to the structural stability of the article. This is made possible by being able to carefully control the geometry of the tantalum material during processing. A method for producing such material includes extruding a billet filled with a (preferentially geometrically uniform) mixture of rods of tantalum and an extrudable metal. When the billet has been sufficiently reduced in size and severed, the extrudable metal is removed by selectively dissolving with acid. In addition to the above advantages, the resulting article is particularly adapted for use in super-miniaturization applications.

摘要翻译： 生产的钽电极材料具有非常低的曲折度，特别低的ESL和ESR，可能延长高频性能，非常高的体积效率和减少每个电极的钽消耗量。 电极材料的特征在于具有由间隔开的间隔开的由钽板隔开的横截面，导致高密度（体积效率）电极。 这些板是电互连的，这也增加了制品的结构稳定性。 这可以通过在加工过程中仔细地控制钽材料的几何形状而实现。 制造这种材料的方法包括挤出填充有（优选几何均匀的）钽棒和可挤出金属的混合物的坯料。 当坯料的尺寸已经被充分地减小并被切断时，可选择地用酸溶解去除可挤压的金属。 除了上述优点之外，所得到的制品特别适用于超小型化应用。
