The diffraction peaks at 2θ = 28.5°, 47.4°, 56.2°, and 76.5°can be indexed to the diffraction peaks of silicon. The broad peak at approximately 25.5° is attributed to that of GNS. No peaks of SiC phases are found, implying the obtained nanocomposites are free of SiC during the ball milling process.
