J. M. Alalkawi, Ghada Adel Aziz and Hussain A. Aljawad University of technology,Iraq ABSTRACT Nanocomposites are materials fabricated from two or more materials with different mechanical and electrical properties. Combining these materials produce a new designed material with new and better properties differ from the individual components .In recent years nanocomposites have been developed and employed almost in all industries . The current study deals with fabricating a hybrid composite ( when there are a minimum of three materials , the composite is called as hybrid composite ) . Pure aluminum 99.6 % as the base matrix and Iron oxide Fe2O3 (alpha) and aluminum oxide Al2O3 (alpha alumina) . Fe2O3 weight percentage (wt%) is varied ( 1.5 , 2.5 and 5 % by weight ) and the wt% of Al2O3 is held constant (2 wt%) . The new designed nanocomposite was produced using Powder Metallurgy (P/M) method . This method has been widely used for fabricating aluminum matrix composites (AMCs) due to it is low costs and gives high accuracy as well as the ease of using . The matrix used was aluminum powder with an average particle size of (60μm) with 99.6% purity and Fe2O3 ( 99% purity and 30 nm particle size ) and Al2O3 with (99.5% purity and 14-20 nm particle size ) . The experimental results revealed that the microstructure images of composites showed uniformly distributed of Fe2O3 and Al2O3 in aluminum matrix . The maximum compressive strength (CS) and hardness (HV) are 152 MPa and 47.2 respectively in composite containing (1.5 Fe2O3 + 2 Al2O3 ) wt% . The improvement percentage was recorded to be 30% and 18.5% for CS and HV respectively . The electrical properties of the composites were enhanced due to addition the nanohybrid Fe2O3 + Al2O3 nanomaterials. The maximum conductivity was observed in composite including (1.5% Fe2O3 + 2% Al2O3 ) which is equal to 69521 ( 〖Ω.m )〗^(-1) while the zero nano exhibited 1170 ( 〖Ω.m )〗^(-1) . Also the conductivity for all composites are higher than that of matrix. The conductivity increased with increasing the frequency Keywords: hybrid nanocomposites, powder metallurgy, compression tests, conductivity and resistivity.
