Aluminum alloys and composites
are used in automobile and aerospace industries due to good mechanical
properties, higher corrosion resistance and light weight. The compression test
of materials at elevated temperature is useful to study the flow stress,
workability, and the analysis of the processing conditions. In this paper, ring
specimens produced from Al 6061 /15%SiCp composite were subjected to uniaxial hot compression
tests 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.
