Self-propagating high-temperature synthesis of (W, Ti) C powders

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 3–5 µm.
