Abstract

In this study, W-Mn matrix composites reinforced with 2 wt% of 24h pre-milled VC particles were mechanically alloyed for 3h, 6h, 12h and 24h. The W-Mn matrix was prepared by mechanical alloying of the powder blends of W-1wt.% Mn and W-3wt.% Mn for 6h. The effects of the manganese amount and the mechanical alloying duration on the microstructural and mechanical properties were investigated. Microstructure and phase characterizations of composite powders and sintered samples were carried out via SEM and XRD analyses. Furthermore, density measurements of as-consolidated and sintered samples and hardness measurements of sintered samples were carried out.
