Aluminum matrix particulate reinforced
composites are of significant interest to industry, but it’s difficult to
provide stable properties for this group of material. The mechanical properties
of metal matrix composites are deeply influenced by the distribution of
reinforcement particulates in the matrix. In this paper uniformity of SiC
particles distribution in Al-based composites produced by stir casting and
powder metallurgy technique is assessed. Analysis is carried out by means of
classical and computer quantification metallographic image analysis methods. In
addition, we suggest setting hardness distribution in cross section of samples
as an indicator of reinforcement distribution uniformity in the matrix.
