Conventional stir casting process has been employed for producing discontinuous particle reinforced metal matrix
composites for decades. The major problem of this process is to obtain sufficient wetting of particle by liquid metal and
to get a homogenous dispersion of the ceramic particles. In the present study, aluminium metal matrix composites were
fabricated by different processing temperatures with different holding time to understand the influence of process parameters
on the distribution of particle in the matrix and the resultant mechanical properties. The distribution is examined
by microstructure analysis, hardness distribution and density distribution.
