Abstract
This paper focuses on synthesis of Silicon Nitride reinforced Al6061 based composite by liquid metallurgy technique and hot forging. The developed composites have been characterized for its microstructure and thermal conductivity studies using parallel conductance method under cast and forged conditions. Thermal conductivity results have shown that with the increase in reinforcement content the thermal conductivity tend to decrease drastically. However, secondary processed matrix material and composites have shown enhancement in the conductivity compared to primarily processed materials. Influence of temperature and possible thermal conductance mechanisms have been discussed.
