    Abstract: A die comprises metal-rich sections which form an inner wall and an outer wall of the die, respectively. Gradient sections are disposed adjacent to the metal-rich sections, respectively. Further, a ceramics-rich section is disposed between the gradient sections. A punch comprises an inner ceramics-rich section, a gradient section, and an outer metal-rich section. In the die, the composition ratio of metal gradually decreases from the metal-rich sections to the ceramics-rich section. Similarly, in the punch, the composition ratio of the metal gradually decreases from the metal-rich section to the ceramics-rich section.

    Abstract: A low CTE metal-ceramic composite material featuring carbon fibers reinforcing a matrix featuring silicon metal or silicon alloy. The fibers have a low coefficient of thermal expansion (CTE) in the axial direction, and preferably negative. The principles of making Si/SiC composites can be adapted to produce the instant Si matrix composites. The CTE of the composite body depends not only upon the relative CTE's of the fibers and matrix, and their relative amounts (e.g., loadings), but also upon the relative elastic moduli of the fibers and matrix. Thus, Si/SiC matrices produced by a reaction-bonding process inherently possess low CTE, but the instant inventors prefer to make such composites having relatively large fractions of unreacted silicon, thereby driving composite CTE lower still. Here, the carbon fibers are protected from reaction with the silicon infiltrant with one or more materials disposed between the fibers and the infiltrant. Providing at least a degree of toughness or impact resistance can also be realized in these composites. Laminates produce Isotropic or quasi-isotropic properties in the composite body can be realized by, for example, providing the fibers in the form of cross-plied laminates featuring the fibers in parallel or woven arrays.

    Abstract translation: 低CTE金属陶瓷复合材料，其特征在于碳纤维增强了具有硅金属或硅合金的基体。 纤维在轴向上的热膨胀系数（CTE）优选为负。 制备Si / SiC复合材料的原理可以适用于生产即时Si基复合材料。 复合体的CTE不仅取决于纤维和基体的相对CTE以及它们的相对量（例如载荷），而且取决于纤维和基体的相对弹性模量。 因此，通过反应连接工艺产生的Si / SiC基体固有地具有低CTE，但是本发明人优选制备具有相对大的未反应硅的分数的复合材料，从而驱动复合CTE较低。 这里，保护碳纤维免受与硅浸润剂的反应，其中一种或多种材料设置在纤维和浸润剂之间。 提供至少一定程度的韧性或抗冲击性也可以在这些复合材料中实现。 通过例如提供以平行或编织阵列的纤维为特征的交叉层叠体的形式的纤维，可以实现层合体在复合体中产生各向同性或准各向同性的特性。
