چکیده
|
In this study al-5 (vol) % sicp nanocomposite 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 nanocomposite powder microstructure with time have been investigated by x-ray diffraction (xrd), x-ray mapping, and scanning electron microscopy (sem) analyses. the morphologies of the nanocomposite powders obtained after 25 h of milling have also been studied by transmission electron microscopy (tem). the results showed that nanocomposite powders were composed of near-spherical particles and, moreover, the sic particles were uniformly distributed in the aluminum matrix
