Özet
In this study, the microstructures, hardness values and compressive strength of SiC reinforced Al metal
matrix composites in different rates produced by powder metallurgy (PM) method have been examined.
Al powders which has 99% purity and 1-210 µm size, and SiC powders which has 98.5% purity and 1-45
µm size were used in experiments. These powders were weighed in proportions pure Al, 4% SiC/Al, 8%
SiC/Al, 12% SiC/Al, 16% SiC/Al via precision balance. A mechanical mixing device was used in order to
homogeneously mix of the weighed powders. These mixtures were pressed under pressure of 475 MPa.
All pressed materials were made into composite by sintering for 120 minutes at 580 ºC. Microstructures,
hardness values and compressive strength of the composites were analyzed by polishing the surfaces of
the composites. As a result of analysis, it was observed that the SiC reinforces were uniformly dispersed
in Al matrix, the hardness values of the composite increased with increasing reinforcement rate and the
compressive strength values of the composites were similar to one another
