Abstract

In this research elements of the raw materials used to form MoSi2-TiC NANOCOMPOSITE. The plan in this Research procedure was based on combustion synthesis, mechanical activation mechanism (MASHS). Initially Mo, Si, Ti and C elemental powder were weighed by stoichiometry ratio and were milled with weight ratio of ball to powder 5 to 1, 10 to 1 & 15 to 1, milling time 4, 8, 12 hours with 250 and 300 rpm by the planetary mill. After wards the milled powders were compacted to pellet form by uniaxial press and synthesized samples were done in an atmospheric argon controlled tubular furnace with a temperature between 700 – 1100oC. To identify phases, XRD analysis was used and to evaluate morphology, SEM and TEM images were used. XRD patterns from synthesized samples with (MASHS) method show a successful composite MOLYBDENUM DISILICIDE - TITANIUM CARBIDE synthesis. Results show the best process conditions for synthesis MoSi2-TiC NANOCOMPOSITE with MASHS method was: milling duration about 4 hours, ball to powder weight ratio 15 to 1, mill rotation speed 300 rpm, constant pressure press 300MPa and temperature 850oC. The grain size calculation by reitveld method showed the size of TITANIUM CARBIDE crystallite and MOLYBDENUM DISILICIDE in optimum condition of approximately 28 nm and above 100 nm respectively. The images of SEM and TEM proved that a nanostructure composite has been synthesized.
