研究了SiC与铝液的反应。透射电子显微镜（TEM）观察表明，无压烧结SiC与Al的界面处形成了碳化铝（Al 4C 3）相。而在反应烧结SiC-Al界面处未检测到Al 4C 3相。这种微观结构的差异导致接头弯曲强度的变化。在973 ~ 1473 K的温度范围内，将SiC和Al粉末的混合物在真空中加热反应，并用X射线粉末衍射分析了反应产物。结果表明，在Al中形成了Al_4C_3和Si，Si的加入降低了SiC与Al的反应程度。
Reactions between SiC and liquid aluminium were studied. Transmission electron microscopy (TEM) showed that aluminium carbide (Al4C3) phase was formed at the interface between pressureless sintered SiC and aluminium. In contrast, the Al4C3phase was not detected at the reaction sintered SiC-Al interface. This difference in microstructures results in the change in bending strength of the joints. Mixtures of SiC and aluminium powders were heated to react in vacuum in the temperature range 973 to 1473 K and the reaction products were examined using X-ray powder diffraction. It was confirmed that Al4C3and silicon were formed, and that the extent of reaction between SiC and aluminium was decreased by the addition of silicon into aluminium.
