The Cu(80%)–NbC(Nb)–WC(W) alloys at low-frequency vibration of liquid-solid compositions at 1300°C were obtained. Their structure was studied. The formation of the (Nb,W)C solid solution in Cu–NbC–WC and Cu–Nb–WC systems was revealed. The decomposition structure of of the (Nb,W)C solid solution with the allocation of NbC carbide from it and with sizes close to micron ones was formed in the Cu–NbC–WC alloy.
