Description

In this study Al-5 (Vol)percentSiCp nano composite powder has been successfully synthesized by high-energy planetary milling of Al and SiC powders for a period of 25 h at a ball-to-powder ratio of 15:1. The changes of the lattice strain, the crystallite size of the matrix phase, and the nano composite powder microstructure with time have been investigated by X-ray diffraction, X-ray mapping and scanning electron microscopy analyses. The morphologies of the nano composite powders obtained after 25 h of milling have also been studied by transmission electron microscopy. The results showed that nano composite powders were composed of near-spherical particles and, moreover, the SiC particles were uniformly distributed in the aluminum matrix.
