ni-hard4 white cast iron is excellent wear resistant material and has been widely used in wearaffected equipment operated under extreme conditions, such as in mineral processing, cement, copper and iron manufacturing. in this study the effect of titanium addition (1.2, 0.7 and 0.2 wt.%) to the ni-hard 4 cast iron with the nominal composition of si= 1.5%, mn=0.5%, c=3%, p=0.05%, s= 0.05%, mo= 0....
the combustion process of tio2- 2mg- c and 3tio2-4al-3c systems in a tubular furnace was investigated. tic has been synthesized by the magnesiothermic reaction from a mixture of compacted powders of tio2, mg and charcoal as starting materials in the presence and absence of nacl. the effects of temperature, pressure, and the stoichiometry ratio in the reaction yield have been studied. the result...
Influence of titanium carbide on the interlaminar shear strength of carbon fibre laminate composites
The potential use of carbon fibre laminate composites is limited by the weak out-ofplane properties, especially delamination resistance. The effect of incorporating titanium carbide to the mesophase pitch matrix precursor of carbon fibre laminate composites on interlaminar shear strength is studied both on carbonised and graphitised composites. The presence of titanium carbide modifies the opti...
To achieve optimal mechanical properties in high manganese steels, the precipitation of nanoprecipitates of vanadium and niobium carbides is under investigation. It is shown that under controlled heat treatments between 850°C and 950°C following hot deformation, few-nanometre precipitates of either carbide can be produced in test steels with suitable contents of vanadium or niobium. The structu...

The microstructure of three different nanocrystalline materials with hexagonal crystal structure are studied by X-ray diffraction peak profile analysis. The crystallite size distribution and the dislocation structure are determined in plasmathermal silicon nitride powder, sintered tungsten carbide and severely deformed titanium and are compared with transmission electron microscopy (TEM) result...
The combustion process of TiO2- 2Mg- C and 3TiO2-4Al-3C systems in a tubular furnace was investigated. TiC has been synthesized by the magnesiothermic reaction from a mixture of compacted powders of TiO2, Mg and charcoal as starting materials in the presence and absence of NaCl. The effects of temperature, pressure, and the stoichiometry ratio in the reactio...

boron carbide is one of the hardest materials. the combustion method was used to synthesize b4c-tib2 nanocomposite powder in a b2o3-mg-tio2-c system. an experimental study of the formation of b4c–tib2 nanoparticles was conducted in the thermal explosion mode. a mixture of b2o3:tio2:mg:c at a molecular ratio of 3:1:12:1 was chosen to obtain the b4c–tib2. this powder mixture was milled for differ...
