The fracture process and the structure changes of the multi-walled carbon nanotubes (MCNT) during the mechanical ball milling process were investigated and the samples of ball milled powder were observed by SEM. The results indicate that the MCNT turned into nano-whiskers or nano-particles during the ball milling process. The pre-milled MCNT could be distributed in Cu powders homogeneously. The bulk MCNT / Cu nanocomposite were fabricated by hot pressing the mixed MCNT / Cu powders at a temperature of 1073 K under a pressure of 20 MPa and the microstructure of the composites were investigated. It has been found that the multi-walled carbon nanotubes distributed in copper evenly.

Partially reacted mixtures of Pb(ZrxTi1−x)O3 and its corresponding starting oxide components were obtained by a high-energy ball milling process. The partially reacted powders were characterized by x-ray diffraction and scanning electron microscopy techniques. The sintering behavior of the milled mixtures has demonstrated a distinct volumetric expansion before the densification of the samples, which clearly shows the occurrence of a reactive sintering process of the partially reacted powders. Such process requires a lower densification temperature as compared with the PZT powders produced by the conventional solid-state reaction process. PZT ceramics were found to form directly from the partially reacted powders sintered at 900–1200 °C. The dielectric and ferroelectric properties of the PZT ceramics as a function of sintering temperature and milling time were also studied and discussed.
