Aluminum alloys and composites are used in automobile and aerospace industries due to good mechanical properties, higher corrosion resistance and light weight. In this paper, ring specimens produced from Al 6061 /15%SiCp composite were subjected to uniaxial hot compression test to invistigate the deformation behavior of the material. The tests were performed at high temperatures ranged from 300 oC to 500 °C and strain rates of 0.008 s−1 to 2.7 s−1. The flow stress-strain curve at different strain rates and temperatures was determined. The regression analysis was performed to predict the flow stress during the compression test. The comparison between the experimental and theoretical results was also conducted. In addition, finite element method was applied to simulate and validate the compression behavior of the composite ring. Furthermore, the erosion-corrosion tests by slurry pot method were conducted to examine the influence of SiC particles on erosion corrosion resistance of the material. The results showed that the flow stress of the Al6061/15/vol.%SiCp composite is correlated directly with temperature and strain rate. Also, the erosion corrosion resistance increased with adding SiC particles to Al 6061 alloy.
