摘　　要：研究了纳米晶W -Cu微粉在模压及冷等静压工艺下成形特性的对比 .试验证明 60 0MPa压力下 ,冷等静压成形工艺较模压工艺获得的坯体致密度高于 1 5 % ,但冷等静压工艺中的包套除气对坯体致密度及性能有较大的影响 .Compares characters of nano crystalline powder of W-Cu by mould pressing(MP) or cold isostatic pressing (CIP) and concludes from the results that the density of specimen by CIP was 15% more than that by MP in 600 MPa, but air exemption of airtight envelope in CIP had greater effect on density and capability of pressed specimen.
