Now a days, Metal matrix composites have been regarded as one of the most proposition grouping in composite materials. There is lot of demand in the modern society from the working life in aluminum metal matrix composites. The best example for this is application of the aluminum and its alloys as substitution for steel and similar materials. Specific aluminum alloys have good mechanical properties, but poor Tribological characteristics. The thermal characterization of hybrid metal matrix composites has imperative impact in a wide range of applications. The thermal conductivity is the most important properties of Metal Matrix Composites (MMCs). Since nearly all Metal Matrix Composites are used in various temperature ranges, measurement of thermal properties of MMC’s as a function of temperature is necessary in order to know the behavior of the material. Thermal conductivity is one of the primary terms commonly used in the research of materials. The thermal characterization of composite materials has received large consideration and has become governing in materials science and engineering. In this paper, the thermal conductivity investigation of Al6351, Sic and Gr. hybrid metal matrix composites by varying percentage reinforcement of Sic (0,2,4,6,8,10%) and Gr.(10,8,6,4,2,0%) have been carried out. Al based composite reinforced with Sic and Gr. particle have been prepared by squeeze casting technique. The main advantage of going for squeeze casting is the material wastage is less and the low level of porosity. The investigation of thermal conductivity behavior of hybrid composites with varying percentage reinforcement at lower division have been emphasized.
Keywords- Al6351, sic, graphite, squeeze casting, thermal conductivity.
