摘要
Aluminum powder with an average particle size of 10 mu m was mechanically mixed thoroughly with 5 wt% fine Al2O3 powder with an average particle size of 3.7 mu m reinforcement. Iron particles with an average particle size of 0.5 nm and copper particle size of 10 mu m were added to the base matrix Al-5Al(2)O(3). The composite material was produced by a single action hot compaction of the powders. Aluminum-alumina composites containing iron, copper, and iron with copper were produced through mixing the atomized matrix alloy powder with 5 wt% of Al2O3 particles, then cold pressed for 5 min, degaussed, and hot pressed. The hot pressing technique was performed up to 500 degrees C at 318.34 MPa for 5 min dwell time. The Al5-Al2O3 composites were examined for hardness, compression flow properties, and wear analysis.
