- Effect of Firing Temperature and Holding Time on Characterization of Al/SiC Metal Matrix CompositesProduced by Pressureless Infiltration. The production of Al-SiC metal matrix composite can be carried out bypressureless metal infiltration processs (PRIMEX). The experiment was conducted using aluminium AC2B ingot as amatrix and 50%Vf SiC powder as a reinforcement which is mixed with 10% Mg powder for wetting agent. Thevariables of this experiment are holding time and firing temperature to investigate the effect of these conditions onmechanical properties of Al-SiC metal matrix composites. Holding time was conducted for 2,5,8,10,12 hours and firingtemperatures was 750, 800, 900, 1000, 1100°C respectively.. The composites produced are analysed both mechanicalproperties and metalography such as densities, porosities, hardness, as well as wear rate. The results showed that thelonger holding time and increasing firing temperature will increase mechanical properties of Al-SiC metal matrixcomposites, and it is found that the optimum mechanical properties at 1000°C for 10 hour.Keywords: Al-SiC metal matrix composite, pressureless infiltration.
