Effects of Adhesive and Interphase Characteristics between Matrix and Reinforced Nanoparticle of AA7175/AlN Nanocomposites

Theoretical models were unable to examine the overall elastic-plastic response during the deformation of metal matrix composites. On the other hand, numerical micromechanical modeling analysis appears to be well-suited to describe the behavior of these composites. In this article two types of RVE models have been implemented using finite element analysis. Aluminum nitride nanoparticles were used as a reinforcing material in the matrix of AA7175 aluminum alloy. It has been observed that the nanoparticle did not overload during the transfer of load from the matrix to the nanoparticle via the interphase due to interphase between the nanoparticle and the matrix. Due to interphase between the nanoparticle and the matrix, the tensile strength increases from 510.60 to 532.51 MPa.
