摘要：

A new processing technique, spark plasma sintering (SPS), has been used for processing of metallic materials, ceramics, nanomaterials, biomaterials and functionally graded materials(FGM). Our work mainly focused on Ti-Si-C system, including synthesis of TiC/SiC, Ti5Si3/TiC and Ti5Si3/TiC/Ti3SiC2 nanocomposites using Ti, Si, C and SiC powders, as starting powders via SPS. The phase constituent of the samples was analyzed by X-ray diffraction (XRD) techniques and microstructures were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Fracture toughness at room temperature was also measured by indentation tests. The results showed that the nano-composites of Ti-Si-C system could be fabricated by means of reactive sintering method in a relatively short time (< 8 min) and low temperature (< 1500 degrees C), with a fine microstructure (grain size < 500).
