Abstract
Al-7wt.%Si alloy was produced by applying complex shearing to the liquid melt during graphite mould casting. Microstructure was analyzed with optical microscope (OM), scanning electron microscope (SEM) and high-resolution transmission electron microscope (HRTEM). Results show that Si nanoparticles, which can only be conventionally obtained by melt spinning technique for cast Al-Si alloy, are embedded in Al matrix. There is a cubic to cubic orientation relationship (OR) and a semi-coherent interface between Si nanoparticle and Al matrix. Formation mechanism of Si nanoparticles has been discussed.
