Thermal Analysis of Aluminium based Particulate Metal Matrix Composites
To improvise heat sinks performance, heat transfer rate needs to be increased; based on Newton’s Law of
Cooling. Literature review suggested that materials for heat sinks are unexplored so far. Hence this research focuses on novel
class of materials engineered by dispersing ceramic particles in conventional aluminium alloys. Aluminium metal matrix
composites (AMCs) reinforced with micron-sized cubic boron nitride (CBN), Silicon Carbide (SiC) and Aluminium oxide
(Al203) particles were fabricated by bottom tapping stir casting method. By characterizing, all three fabricated different
composition (BN, SiC, Al203) AMCs in which Aluminium Boron Nitride (Al/BN) composites exhibits expected results. The
result shows significant enhancement in thermal conductivity of Al/BN composites than conventional Aluminium Alloy
6061 (AA 6061) and other ceramic reinforced AMCs.
