| Abstract Scope |
Tungsten nanopowder was synthesized using carbothermal reduction route from WO3 powder. It was investigated the effect of addition of prepared nanopowder to hard alloys. Field emission electron microscope was used for morphology investigation. X-ray diffractometry was used to analyze crystalline structure. It was found that addition of nanopowder increased bending strength by 15% compared to regular hard alloy. Effect of contamination of carbon in prepared nanopowder to mechanical properties of hard alloy was discussed |
