초록
A mixture of Al and BN powders was adopted to synthesize AlN matrix composites using the spark plasma sintering-reactive (SPS) synthesis method. The crystalline phases of sintered samples were characterized by X-ray diffraction (XRD). Scanning electron microscope (SEM) and transmission electron microscope (TEM) images of the microstructure revealed that the BN phase was homogeneously distributed in the matrix of synthesized AlN. The effect of sintering temperature on the microstructure and properties of sintered samples was investigated. The results showed that densification of sintered samples was improved and the thermal conductivity exhibited a significant increase with an increase of the sintering temperature.
