Consequences of Interphase between Matrix and Reinforced Nanoparticle on Behavior of AA6262/AlN Nanocomposites

The performance of the metal matrix particulate composite depends, besides the matrix microstructure and the nature of the reinforcement, very significantly on the interphase between matrix and reinforcement. Improvements in mechanical properties have been found by adding a wetting agent. In this article two types of RVE models have been executed using finite element analysis. Aluminum nitride nanoparticles were used as a reinforcing material in the matrix of AA6262 aluminum alloy. It has been ob-served 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. The tensile strength has increased from 305.61 to 314.70 MPa with interphase around aluminum nitride nanoparticle in the AA6262/AlN nanocomposites.
