Abstract |
Due to advantages of mechanical alloying in comparison with liquid state processes, this process has used
a lot to synthesis nanostructured alloy. In the present study, aluminum and silicon elemental powders with
composition Al-5wt % Si were synthesized by mechanical alloying in high energy planetary ball. X-ray diffractometer and scanning electron microscopic were used to study microstructural and morphological changes of
powder particles and formation of solid solution of Al-Si during milling. Crystallite size, lattice strain and lattice parameter were determined by Scherer, Williamson–Hall and Nilson–Reley methods. Minimum crystallite size was 17.895 nm according to Scherer method and 32.644 nm according to Williamson-Hall. Solid solution of Al-Si was formed between 5 h and 30 h, due to crystallite size in nano scale and diffusion process in
mechanical alloying. In addition lattice parameter changes and XRD results prove it.
