Influence of powder particle size on the mechanical properties of SiCp reinforced A.A.7075
Keywords:Composites, Al7075-SiCp, Particle size, Rapid solidification, Ball mili
The influence of powder particle size of 7075 aluminum on the room temperature mechanical properties of 7075-15 vol % SiCp has been studied. The aluminum powder was obtained by argon atomization under rapid solidification conditions. Composite materials were prepared from three different particle sizes, namely: < 50 μm, 50-100 μm and 100-200 μm. These powders were blended with 15 vol % of SiC particles < 5 μm in size by ball milling and then, hot extruded. The best properties of the resulting composites correspond to the material prepared from the smallest particle size. For this case, a clear improvement of the mechanical properties, except for ductility, is obtained. This is attributed to a more homogeneous distribution of the reinforcing SiC particles.
