采用全自动压汞仪对传统的模压成型和等静压成型的钨坯和钨基孔结构分布进行了研究。结果表明:模压成型的钨坯平均孔径为1.02μm,钨基平均孔径1.41μm,孔径分布不均匀,钨基中小孔径与大孔径的量较多;等静压成型的钨坯平均孔径为1.18μm,孔径分布范围窄,钨基平均孔径为1.55μm,1.00～2.20μm的孔径占总孔径的68.15%。
The distribution of tungsten blankets and tungsten matrix in traditional molding and isostatic pressing was studied by using automatic mercury porosimeter. The results show that the average diameter of the tungsten billet is 1.02μm, the average pore diameter of tungsten is 1.41μm, the pore size distribution is not uniform, , The pore size distribution is narrow, the average pore diameter of tungsten is 1.55μm, the aperture of 1.00 ~ 2.20μm accounts for 68.15% of the total pore size.
