        Abstract
        The self-propagating high-temperature synthesis (SPS) of TiSi and T Si,AL) powders was investigated. Elemental powders of titanium, silicon and aluminum were used for the synthesis. The sample powders were investigated by means of x-ray diffraction (XRD) with Cu radiation. It was observed that the presence of aluminum in subsequently ignited Ti-Si powder mixtures had led to reduction in the ignition temperature to between 575 °C and 590 °C. Using XRD analysis, C-54 and C-49 Ti(Si,Al) phase fields of the sample powders were identified. It was found from SEM measurements that the C-49 phase was not uniform exhibiting regions with variation in both aluminum and silicon content.
