It was found that the alloy relative density can be improved with the additionof Cu when Cu content is not very high, and W95Ni3Cu2 alloy with full density can be obtainedon the sintering condition. However, with the Cu content further increasing, the relative densitychange of W-Ni-Cu alloy and W-Fe-Cu alloy shows difFerent trends: the former tends to decreaseobviously, but the latter shows little change. According to the analysis results, the element Cuhas different effects on the activation capability of Ni and Fe during sintering of the tungstenalloys. 关 键 词：Fe Cu Densification of W-Ni-Cu and W-Fe-Cu Alloys at 1573 K NI
