摘　　要：目的　研究纳米晶 W(Cu)合金微粉在真空烧结实验中的烧结行为 .方法　将纳米晶 W(Cu)合金微粉压胚放入真空炉内进行烧结 .结果　在 1 0 0 0℃的真空烧结温度下保温 3 0 min,纳米晶合金的晶粒度小于 3 5 nm;同时 ,W(Cu)固溶体未发生分解 .结论　 W(Cu)Aim\ Studies on sintering action of nanocrystalline powder of W(Cu) by MA(machenical alloying) are presented. Methods\ The pressed samples are sintered in vacuum stove and measured. Results\ It is shown that the grain size is less than 35 nm and the solid solution remains undecomposed after vacuum sintering under the temperature up to 1 000 ℃ and held on 30 min. Conclusion\ W(Cu) solid solution is a stable phase.
