Effect of Sintering Temperature on Mechanical Properties of Aluminum Composites

Using Al, Al2O3 and SiC, different types of composites have been prepared in this experiment. Green compacts of Al composites were made at a compressing load of 1 ton and 2 ton respectively. These compacts were sintered at two different sintering temperatures of 400 °C and 450 °C in an oxygen free environment using muffle furnace for one hour followed by annealing process which took 12 hours. Sintered compacts were then sintered to micro structural examination and mechanical properties evaluation. Higher hardness has been attained for the composites containing 2.5 SiC. Attempts have been made to describe the influence of sintering temperature on the microstructure and properties of Al Al2O3 SiC composites. Samples are prepared of 100 Al, 97.5 Al 2.5 Al2O3, 92.5 Al 7.5 Al2O3, 95 Al 2.5 Al2O3 “ 2.5 SiC, 92.5 Al 5 Al2O3 “ 2.5 SiC, 95 Al “ 5 Al2O3. The main objective of this experiment is to determine the factors that can increase hardness of Al composites.
