Abstract

In this study, tungsten matrix composites reinforced with 2 wt% TiC particles were mechanically alloyed (MA'd) for 3h, 6h, 12h and 24h. 1 wt% Ni is used as sintering aid which is added before and after mechanical alloying. Microstructural and phase characterizations of composite powders and sintered samples were carried out via SEM and XRD analyses. Furthermore, density and hardness measurements of as-consolidated and sintered samples were carried out. Additionally, DSC experiments were conducted to investigate the sintering behavior of the MA'd powders.
