Preparation of C/Cu Composite Powders by High-Energy Ball Milling
Cu-4%C mixed-powder consisting of rough copper powder and graphite powder was separately mechanical alloyed by high energy ball milling. The phases and micrograph of these powders were determined by X-ray diffraction and scanning electron microscopy (SEM). The results show that increase of the lattice parameter of copper with milling times, up to a saturation value of about 24h; The absence of graphite reflections in X-ray diffract grams for longer milling times.
