The Synthesis Of Nanocomposites (MoSi2-20% TiC) is activated by chemical Combustion Synthesis Method (COSHS)

Add titanium carbide in the compound molybdenum disilicide to increased mechanical strength. in this research element of the raw materials used to form MoSi2-TiC nanocomposite. the plan in this research procedure was based on combustion synthesis, chemical activation mechanism (COSHS). in this study, activation of elemental powders Mo, Si, Ti and C were used in chemical oven. first, on the basis of stoichiometric silicon powder raw materials including metal powder, molybdenum, titanium and carbon powder were prepared on the basis of 20% by weight of titanium carbide. to identify chemical compounds that react with itself, provides the heat necessary to react original composition (chemical oven), of compounds that have high ΔG was used. powders and tablets are pressed by uniaxial compaction of composite samples were prepared and chemical oven. synthesizing is done in atmospheric argon controlled tubular furnace the temperature between 700 - 1100 °C. to identify phases, xrd analysis and to evaluate morphology, sem and tem images were used. results show that the best process conditions for synthesis MoSi2-TiC nanocomposite with COSHS method were: temperature 850 °C selected as optimum conditions and composition (8Al 4Mg 3SiO2 5TiO2) as suitable chemical oven. the grain size calculation by reitveld method showed the size of titanium carbide crystallite and molybdenum disilicide in optimum condition of approximately was 77 nm and above 100 nm respectively. considering the images of sem and tem proved that a nanostructure composite has been synthesized.
