    An Al2O3TiB2 nanocomposite was successfully synthesized by the high energy ball milling of Al, B2O3 and TiO2. The structures of the powdered particles formed at different milling times were evaluated by Xray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Thermodynamic calculations showed that the composite formed in two steps via highly ...
