Mechanical alloying was used to synthesize in-situ copper based composite reinforced by binary niobiumtitanium-carbide from Cu, Nb, Ti and graphite powder mixture. The nominal composition was correponded to Cu-30 vol.% (Nb,Ti)C. XRD patterns showed that (Nb, Ti)C was not formed in the as-milled powder after 5 hours of milling but was precipitated with a subsequent sintering at 900oC. Milling time has showed a great influence on both mechanical and physical properties of the sintered composite pellets |
