Development and Characterization Investigations of Mechanically Alloyed and Sintered W-2 wt VC-1 wt Ni Composites

摘要

In this study, tungsten matrix composites reinforced with 2 wt% VC particles were mechanically alloyed (MA'd) for different time durations such as 3 h, 6 h, 12 h and 24 h. 1 wt% Ni is used as a sintering aid which is added before and after mechanical alloying to investigate both effects of MA and activated sintering. Microstructural and phase characterizations of composite powders and sintered samples were carried out via SEM and XRD analyses. Additionally, density and hardness measurements of the sintered samples were carried out in order to understand the mechanical properties of the developed composites better.
