    Abstract: An assembly for the preparation of ceramic composite structures includes a segmented container (12) within which a permeable filler is retained and a parent metal body (20) is contacted with the bed (18) of permeable filler. The segmented container (12) is comprised of one or more segments made of a material, such as an Inconel alloy, which has a coefficient of thermal expansion which is significantly greater than that of the filler. The segments are arranged to define between or among them one or more expansion joints which are effective to accommodate circumferential thermal expansion of the segments to thereby inhibit or prevent volumetric expansion of the container (12). A method of forming ceramic composite structures includes heating the resulting assembly to melt and oxidize the parent metal, (20), e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the mass of filler to embed it and thus form the composite structure.

    Abstract: An assembly for the preparation of ceramic com­posite structures includes a segmented container (12) within which a permeable filler is retained and a parent metal body (20) is contacted with the bed (18) of per­meable filler. The segmented container (12) is comprised of one or more segments made of a material, such as an Inconel alloy, which has a coefficient of thermal expan­sion which is significantly greater than that of the filler. The segments are arranged to define between or among them one or more expansion joints which are effec­tive to accommodate circumferential thermal expansion of the segments to thereby inhibit or prevent volumetric expansion of the container (12). A method of forming ceramic composite structures includes heating the re­sulting assembly to melt and oxidize the parent metal, (20), e.g., aluminum, to form a polycrystalline material comprising an oxidation reaction product which grows through the mass of filler to embed it and thus form the composite structure.

    Abstract translation: 用于陶瓷复合结构的制备的一个组件包括在其内的可渗透填料保留的分段容器（12）和母体金属体（20）与可渗透的填充物床（18）接触。 分片容器（12）包括的材料制成，颜色的一个或多个段的：如在铬镍铁合金，其具有的热膨胀系数的所有其比填料的显着更大。 所述段被布置之间或它们的一个或多个膨胀节哪些是有效的，以适应所述段的周向的热膨胀，从而抑制或防止所述容器（12）的体积膨胀之间界定。 形成的陶瓷复合结构包括加热所得到的组件以熔化和氧化母体金属（20）一种方法，例如，铝，以形成包含氧化反应产物的多晶材料，该材料通过填料的质量增大到它嵌入并因此 形成复合结构。
