摘要： A net shaped ceramic-reinforced aluminum matrix composite is provided by forming a permeable mass of ceramic material with a defined surface boundary having a barrier, and contacting a molten aluminum-magnesium alloy with the permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume, balance nonoxidizing gas, e.g. hydrogen or argon. Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures until it reaches the barrier. A solid body of the alloy can be placed adjacent to a permeable bedding of ceramic material having a barrier, and brought to the molten state, preferably to at least about 700.degree. C., in order to form the net shape aluminum matrix composite by spontaneous infiltration. In addition to magnesium, auxiliary alloying elements may be employed with aluminum. The resulting composite products may contain a discontinuous aluminum nitride phase in the aluminum matrix.

摘要： Current top performing SAPI systems are B4C-containing (hot pressed B4C or reaction bonded B4C). These systems will not function well versus future WC/Co threats due to the inability of B4C to withstand high pressure impacts. New approaches will be needed for next generation SAPI ceramics. Three related concepts are disclosed herein, each of which will lead to improved reaction bonded ceramics for next generation SAPI applications. The first concept aims to reactively heat treat reaction bonded B4C, causing. SiC and SiB6 to form at the expense of B4C. The second approach will add Ti to the system, thus allowing TiC and TiB2 to form at the expense of B4C. Finally, the third concept will evaluate the use of finer particle sizes, thus improving the static properties of the ceramics (with the aim of enhancing multi-hit performance). In all cases, preliminary work has been conducted to demonstrate the viability of the concepts. This will lead to a new family of advanced armor ceramics. These new armor ceramics will allow the modern soldier to be better protected versus next generation, high level threats (e.g., high pressure WC/Co projectiles) with a more ergonomic package (lower weight, less bulk). Further, the results disclosed herein will yield improvement versus the current tool steel threats.
摘要翻译：目前高性能SAPI系统是含B4C（热压B4C或反应键合B4C）。由于B4C不能承受高压冲击，这些系统对于未来的WC / Co威胁将不能很好地运行。下一代SAPI陶瓷将需要新的方法。本文公开了三个相关概念，每个概念将导致用于下一代SAPI应用的改进的反应结合陶瓷。第一个概念旨在反应性地热处理反应结合的B4C，导致。 SiC和SiB6以B4C为代价形成。第二种方法将Ti添加到系统中，从而使TiC和TiB2以B4C为代价形成。最后，第三个概念将评估使用更细的粒径，从而改善陶瓷的静电特性（目的是提高多重击打性能）。在所有情况下，已经进行了初步的工作来证明概念的可行性。这将导致一个新的先进装甲陶瓷家族。这些新的装甲陶瓷将使现代士兵得到更好的保护，与下一代高水准的威胁（例如，高压WC / Co射弹）相比，具有更符合人体工程学的包装（重量轻，体积较小）。此外，本文公开的结果将相对于当前的工具钢威胁产生改进。

摘要： A metal matrix composite (MMC) material that is castable, or can be rendered castable, is melted and cast into a mold or crucible, and at least a portion of the plurality of reinforcement bodies is permitted to at least partially settle out of their suspension in the molten matrix metal. The casting is solidified, and the sparsely loaded supernatant is separated from the zone of the casting containing the sediment—either by cutting, sawing, etc., or by decanting the supernatant when the casting was still in a molten condition. In a preferred embodiment, during the settling and/or the solidification process, mechanical energy, such as in the form of oscillations, is applied to the MMC melt. The applied energy permits the reinforcement bodies to nestle and pack more efficiently, thereby increasing their volumetric loading in the cast composite.

摘要： Silicon infiltration technology is used to produce ceramic bodies having utility as ballistic armor. In a first aspect of the invention, the ballistic armor includes a reaction-bonded silicon carbide body (RBSC). Good ballistic performance can be advanced by loading the permeable mass or preform to be infiltrated to a high degree with one or more hard fillers, and by limiting the size of the largest particles making up the mass. In a second aspect, the silicon infiltration technology, e.g., siliconizing or reaction-bonding, is used to bond silicon carbide fibers to at least the back surface of a ceramic armor body, thereby enhancing ballistic stopping power. A third aspect of the invention pertains to the ability to engineer RBSC bodies such that there is little dimensional change during processing, thereby permitting high dimensional reproducibility in large-scale production.
