ВЛИЯНИЕ МЕХАНОАКТИВАЦИИ И ТЕМПЕРАТУРЫ ТВЕРДОФАЗНОГО СИНТЕЗА НА СОСТАВ И РАЗМЕР ЧАСТИЦ КАРБИДА ВОЛЬФРАМА

Abstract

This study reports that the preliminary mechanical activation of the W and C powder mix prior to the synthesis allows for obtaining a single-phase WC at significantly lower tempera-tures. This results in smaller mean grain sizes but also increases the amount of free carbon in the WC powder.
