temperature reduction and carbonization technology. Multi-walled carbon nanotube-tungsten carbide composites were prepared by the continuous reduction and carbonization process using multi-walled carbon......
of carbonization temperature, loading degree of TEOS on the structural parameters of these Fe/OMCs were evaluated by X-ray diffraction (XRD) and N2 sorption analysis. The ordering, the specific surface area and the total pore volumes increased with the increase of carbonization temperature from 600 to 850 ℃. And the specific surface area and the total pore volumes increased with the increase of TEOS loading......
and succession carbonization process on mechanical properties were studied with electron omnipotence test equipment, and the fracture morphologies were observed by scanning electron microscopy. The results... direction and impact toughness 2.45 kJ/m2. The compressive strength of composites increases by 22% after successive carbonization process, but the impact toughness decreases slightly, and the fracture model......
of MoSi2. The major carbonization productions are Mo5Si3C and Mo2C. The structure of carbonized layer is loose and there is a large number of circular holes with thickness of about 500-800 μm... phase diagram. The content of Mo2C gradually increases from inner to extra of the sample. The carbonized products form from carbonizing Mo5Si3, rather than a direct carbonization product of MoSi2......
