Abstract
Refractory metal carbides play a critical role in numerous applications due to their exceptional hardness, excellent wear resistance and high-temperature stability. This study successfully synthesizes (Ti, W)C powders by using the self-propagating high-temperature synthesis (SHS) method. The results indicate that the phase structure, morphology, microstructure of (Ti, W)C carbides differ significantly from those of WC carbide synthesized using the similar technique. The (Ti, W)C carbides exhibit angular grain morphology with refined grain sizes due to the addition of Ti. Furthermore, the influence of the Ti/W ratio on the nanohardness of (Ti, W)C was examined, with the (Ti0.6, W0.4)C sample achieving the highest hardness of 35.7 GPa ± 2.8 GPa.
