冲击研磨铍粉及其材料性能

Impact-Attrited Beryllium Powder and Its Material Properties

摘要:

比较了冲击研磨制铍粉和传统的圆盘磨铍粉，结果发现：冲击研磨铍粉和具有粒度分布范围窄，颗粒近球形，氧含量低等优点。用该种粉末制备的铍材，无论是热压还是等静压铍材，其力学性能和性能的各向同性均得到全面改善。

Abstract:

Impact attrition is an advanced technique for the production of bery1lium powder. As compared with discattrited powder, it has many advantages: narrow range of particle distribution, near-spherical particle shape and lower oxygen content. Themechanical properties and isotropy of the resulting hot-pressed or isostatic-pressed compacts are in general improved.
