摘　　要：选取同一FSSS(Fisher Sub-sieve Size)粒度范围内的钨粉为研究对象,研究钨粉形貌团聚个数和粒径分布跨度对压坯强度的影响。结果表明,粉末颗粒粒径差异大,团聚个数多,粒度分布跨度大的粉末,其压坯强度大,反之粉末颗粒均匀,团聚个数少,粒度分布跨度小的粉末,其压坯强度小。Tungsten powders within the same fisher sub-sieve size range are selected as the research object,and the effects of tungsten powder agglomeration quantity and particle size distribution span on billet strength are studied.The results show that powders with large differences in particle size,high agglomeration number,and wide particle size distribution span have higher billet strength.Conversely,powders with uniform particle size,low agglomeration number,and small particle size distribution span have lower billet strength.

关 键 词：钨粉 颗粒团聚个数 粒径分布跨度 压坯强度
