The effect of milling on the particle size and mechanical properties Tungsten Carbide - Cobalt composite were investigated. First, raw materials ratios by mechanical milling for 4 hours at 300 rpm were mixed. The powder in the optimum temperature 1350°C at a rate of temperature rise 50°C / min and shelf life of 4 minutes and the pressure MPa 30 were sintered in SPS. The results indicated nearly...

The main aim of this research was to find the mechanism for the failure of the CoCrMo porous nano-composite by characterizing microstructural changes and fractured surface after compression test. For this purpose, porous nano-composites were prepared with the addition of bioactive glass nano-powder to Co-base alloy with 22.5% porosity by the combination of space-holder and powder metallurgy tec...

Aluminum matrix composites have recently taken an important role in advanced applications because they a good combination of physical and chemical properties. For this reason, work, aluminum composites, with additions ceramic particles (mullite or tungsten carbide), were manufactured order to determine the effect those on mechanical properties microstructure aluminum. The manufacture was carrie...
