Abstract:The effects of preheating temperature and W powder size on the Self-propagating High-temperature Synthesis(SHS) of Ti-W-C system were studied. Preheated mixtures and the decrease of W powder size can accelerate the formation of (W,Ti)C powders. The uniphase (W,Ti)C (WC∶TiC=5∶5) powders with 0.32% free carbon were synthesized from Ti, W, C powders by SHS. The powder size of the product was 3~5μm.

 

Key words: self-propagating high-temperature synthesis(SHS); Ti-W-C system; (W,Ti)C powders
