Abstract

In this study AA7100/6wt% Al2O3 metal matrix composite (AMMS) was
successfully manufactured using stir casting route. The influence of 6wt% Al2O3
content on microstructure, electrical properties and wear
resistance were investigated . The microstructure of composite revealed that
homogeneity of Al2O3 particles in the matrix and also the reinforcement of
grains compared to matrix grains. The homogeneity and reinforcement can be
attributed to enhance the electrical and wear properties and this perhaps could
due to efficiency of stirring process during the casting. The 6wt% Al2O3
content shifted the conductivity and permittivity from reducing in matrix to
increasing in the composite when the frequency increased. The wear resistance
was improved due to addition of  6wt% Al2O3 compared to matrix.
