Abstract
The effect of silicon on synthesis of Ti3AlC2 by spark plasma sintering (SPS) from TiC/Ti/Al powders was investigated. X-ray diffraction (XRD) and scanning electron microscope (SEM) were used for phase identification and microstructure evaluation. The results show that addition of silicon can considerably accelerate the synthesis reaction of Ti3AlC2 and fully dense, essentially single-phase (purity >98%) polycrystalline Ti3AlC2 could be successfully obtained by sintering 2TiC/1Ti/1Al/0.2Si powders at 1 200–1 250 °C under a pressure of 30 MPa. SEM photographs show that the obtained Ti3AlC2 samples from mixtures powders are in plane-shape with a size of about 2–5 μm and 10–25 μm in the thickness dimension and elongated dimension, respectively.
