A new process is proposed to fabricate an intermetallic compound reinforced aluminum alloy matrix composite using the reaction between porous nickel and molten aluminum. The intermetallic compound reinforced aluminum alloy composite was manufactured with the infiltration process method. Porous nickel reacted with molten aluminum at 1023 K, and the intermetallic compound of Al 3 Ni was generated on the surface of the porous nickel. The generated intermetallic compound Al 3 Ni, was delaminated according to the difference of thermal expiation coefficient with nickel, and moves in the direction of aluminum matrix. The effects of processing variables, such as processing temperature, applied pressure and specific surface area of porous nickel on the formation and dispersion behavior of Al 3 Ni were investigated.

Variations in the microstructural properties of Al/Al3Ti nanocomposites, prepared through stir casting technique were examined by x‐ray diffraction analysis using modified Warren Averbach and modified Williamson method. The study revealed that screw dislocations are predominantly generated in the nanocomposites, which contain higher volume percent of Al3Ti. However, at lower Al3Ti content, the finer intermetallic particulates during rolling, are displaced from their initial position, which lead to decrease in percent screw dislocation and subsequent increase in percent edge dislocation. Evolution of the different microstructural features in the nanocomposites were related to the variations in the composition. Textural studies were carried out to understand the effect of compositional variation on the microstructure and properties of the nanocomposites. It has been found that due to the presence of high strain, Brass type structure and the γ fiber are predominant texture component in the nanocomposites. The contribution of microstructure and microstructural parameters, e. g. dislocation density, dislocation type and textural characteristics along with the fractographical analysis were shown to have links with the mechanical properties of the nanocomposites
