%X The mixture of 90%W 7wt%Ni and 3wt? elemental powders was milled in a planetary high-enerpy ball mill. The evolution of the structure during milling and the sintering behavior Of the milled powders were tested. The results showed that by mechanical alloying W(Ni, Fe) supersatumted solid solution with nano-meter size formed, which can enhance the sintering process. Ftilly dense alloy from the milled powders was obtained through solid state sintering. The tensile strength of the obtained alloy is over 900MPa which is comparuble to that of the alloy sintered by traditional liquid-phase sintering from un-milled powders of the same composition.
