    Abstract: Self-supporting bodies are produced by reactive in­filtration of a parent metal (10) into a boron nitride material (12) typically resulting in a body comprising a boron-containing compound, a nitrogen-containing compound and metal. The mass to be infiltrated may contain one or more inert fillers admixed with the boron nitride (12), to produce a composite by reactive infiltration, which com­posite comprises a matrix which embeds the filler material. The matrix, in a composite body containing filler material, comprises one or more of metal, a boron-containing com­pound and a nitrogen-containing compound. The relative amounts of reactants and process conditions may be altered or controlled to yield a body containing varying volume percents of ceramic, metal and/or porosity. The mass to be infiltrated can be contained within a refractory vessel having a venting means included therein.

    Abstract: A ceramic-reinforced aluminum matrix composite is formed by contacting a molten aluminum-magnesium alloy with a permeable mass of ceramic material in the presence of a gas comprising from about 10 to 100% nitrogen, by volume, balance non-oxidizing gas, e.g., hydrogen or argon. Under these conditions, the molten alloy spontaneously infiltrates the ceramic mass under normal atmospheric pressures. A solid body of the alloy can be placed adjacent a permeable bedding of ceramic material, and brought to the molten state, preferably to at least about 700°C, in order to form the aluminum matrix composite by 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 and/or an aluminum nitride external surface layer.

    Abstract translation: 陶瓷增强铝基复合材料是通过使熔融的铝 - 镁合金与可渗透的陶瓷材料接触而形成的，所述陶瓷增强铝基复合材料是在含有约10-100％氮气的气体的存在下，以体积比例平衡非氧化性气体， 氢气或氩气。 在这些条件下，熔融合金在正常大气压力下自发渗透陶瓷块。 合金的固体可以邻近陶瓷材料的可渗透层叠放置，并且进入熔融状态，优选至少约700℃，以便通过渗透形成铝基复合材料。 除了镁之外，辅助合金元素可以与铝一起使用。 所得到的复合产品可能在铝基体和/或氮化铝外表面层中含有不连续的氮化铝相。
