  • Fabrication of a Nano‐Si3N4/Nano‐C Composite by High

    Apr 11 2007 · A nano‐Si 3 N 4 /5 wt nano‐C composite was successfully fabricated for the first time via high‐energy ball milling followed by spark plasma sintering. The milling promoted the amorphization of the starting powders most of the carbon particles were transformed into nano‐size and embedded in the amorphous phase.

  • Microstructure and mechanical properties of aluminium

    The XRD patterns of the ball milled Al alloy and Al-GNSs powder mixtures at different milling times are shown in Figs. 4 and 5 respectively revealing the microstructural evolution of the powder mixing during the ball milling. It is seen that the peak intensity of aluminium decreases with the increase of milling times up to 20 h.
